This formula is used to calculate the area of a circle using the diameter:
A= 1/4πd².
Rearrange the formula to calculate the diameter of a circle.
d = _____
Answer:
d= 2√a/π
To calculate the diameter, rewrite the formula to isolate D
Because a negative diameter doesn’t make sense, eliminate the negative answer from the solution
Simplify further to get the solution
The formula to calculate the diameter of the circle is d = 2 √( A/π )
where d = diameter of the circle
A = area of the circle
What is a Circle?
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the radius of the circle be = r
So , the diameter of the circle = 2r
Now , the area of the circle = πr²
Substituting the value for r , we get
Area of the circle = ( 1/4 ) πd²
So , A = ( 1/4 ) πd²
Now , solving the equation for diameter of circle d , we get
Multiply by 4 on both sides of the equation , we get
πd² = 4A
Divide by π on both sides of the equation , we get
d² = 4A/π
Taking square roots on both sides of the equation , we get
d = 2 √A/π
Therefore , the value of d is 2 √A/π
Hence ,
The formula to calculate the diameter of the circle is d = 2 √( A/π )
where d = diameter of the circle
A = area of the circle

a penny is dropped from a height of 144 ft. Calculate the time between when the rock was dropped and when it landed. If we choose "down" as positive and ignore air friction, the function is h(t) = 16t^2 - 144.
answers
t = 9seconds
t = 3 seconds
t = 18 seconds
t = 10 seconds
Answer:
The time of fall is 9 seconds
Step-by-step explanation:
We are asked to find the time between when the penny was dropped and when it landed.
To do this, we have to start with what we are given and see how we can relate it to find what we are looking for.
From the problem, we are given the equation which represents the height which the penny travels as it falls. It is given by
[tex]h(t) = 16t^2 - 144.[/tex] ----------- equation 1
in addition to that, we are also given that h = 144ft at the end of the fall; that is, where t = t max, and h = hmax
Hence, it is safe to say that at the end of the fall, that the heigh is no more changing. This means that dh/dt = 0
We can now differentiate equation 1 above to get
h max = 16t - 0 ------------- equation 2
recall that h max = 144
plugging the value of h max into equation 2, we have
144 = 16t
t = 9 seconds
Therefore the time of fall is 9 seconds
Answer:
t= 3 seconds

Step-by-step explanation:
Este ejercicio ofrece un recurso mnemotécnico para la comprensión y aplicación del Teorema de Pitágoras, el cual establece que el cuadrado de la hipotenusa es igual a la suma de los catetos elevados al cuadrado, siendo cada componente equivalente al área de un cuadrado hipotético, entonces, la expresión algebraica que representa esa relación entre las áreas es:
[tex]25\,cm^{2} = 16\,cm^{2} + 9\,cm^{2}[/tex]
[tex](5\,cm)^{2} = (4\,cm)^{2}+(3\,cm)^{2}[/tex]
Por analogía, tenemos la siguiente expresión algebraica:

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.410.410, point, 4 years; the standard deviation is 1.91.91, point, 9 years.
Use the empirical rule (68-95-99.7\%)(68−95−99.7%)left parenthesis, 68, minus, 95, minus, 99, point, 7, percent, right parenthesis to estimate the probability of a meerkat living less than 16.116.116, point, 1 years.
Answer:
99.85%
Step-by-step explanation:
The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4 years; the standard deviation is 1.9 years.
Use the empirical rule (68-95-99.7%) to estimate the probability of a meerkat living less than 16.1 years.
Solution:
The empirical rule states that for a normal distribution most of the data fall within three standard deviations (σ) of the mean (µ). That is 68% of the data falls within the first standard deviation (µ ± σ), 95% falls within the first two standard deviations (µ ± 2σ), and 99.7% falls within the first three standard deviations (µ ± 3σ).
Therefore:
68% falls within (10.4 ± 1.9). 68% falls within 8.5 years to 12.3 years
95% falls within (10.4 ± 2*1.9). 95% falls within 6.6 years to 14.2 years
99.7% falls within (10.4 ± 3*1.9). 68% falls within 4.7 years to 16.1 years
Probability of a meerkat living less than 16.1 years = 100% - (100% - 99.7%)/2 = 100% - 0.15% = 99.85%
Answer:

Mrs. Delgado purchased notebooks at 2 for $5 and pens
at $2 per package. She spent $19 for a total of 8 items.
How many notebooks and pens did she buy?
Answer:
Mrs. Delgado purchased 6 notebooks and 2 packages of pens.
Step-by-step explanation:
Given that Mrs. Delgado purchased notebooks at 2 for $ 5 and pens at $ 2 per package, and she spent $ 19 for a total of 8 items, to determine how many notebooks and pens did she buy the following calculation must be performed:
5/2 = 2.5
8 x 2.5 + 0 x 2 = 20
6 x 2.5 + 2 x 2 = 19
Therefore, Mrs. Delgado purchased 6 notebooks and 2 packages of pens.

There are different combinations you can do.... for example
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
so Im not sure which :/ but the equation would be:
10x+20y=160

25x+10y=160
there are different combinations of the two so im not sure T_T

There is a total of 45 playoff games over c days. Write the expression of the number of playoff games happening each day.
Answer:
[tex]\frac{45}{c}[/tex]
Step-by-step explanation:
Playoff games played = 45
Number of days taken for the playoff games = c days
Number of playoff games played in one day = [tex]\frac{\text{Number of games played}}{\text{Total number of days}}[/tex]
= [tex]\frac{45}{c}[/tex]
Therefore, expression for the number of playoff games played in a day = [tex]\frac{45}{c}[/tex]
Jim paid a gym membership fee of $50, plus $20 per month. Jim has paid a total of $290 to thegym. Which equation matches this situation?
Answer:
50+20x=290 or 50+(20x12)=290
Step-by-step explanation:
Answer:
50 + 20m = 290
Step-by-step explanation:
The answer is 50 + 20m = 290, because Jim paid a membership fee that was $50. Then each month he paid $20 because of his new membership. Jim never paid $50 a month, that was only his starter fee, but then gradually paid $20 every month so it would be 20m. Hope this helped.

The ______ number in an ordered pair is the y-coordinate and corresponds to a number of the ______.
Answer:
The second number in an ordered pair is the y-coordinate and corresponds to a number on the y-axis.
Step-by-step explanation:
hope this helps you! :)
The second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.
What is Coordinate System?a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.
An ordered pair contains the coordinates of one point in the coordinate system.
A point is named by its ordered pair of the form of (x, y).
In an order pair the first number represents the x coordinate and the second number represents the y coordinate.
To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.
Hence, the second number in an ordered pair is the y-coordinate and corresponds to a number of the y axis.
