To the nearest tenth of a centimeter, how tall is a cylinder with a radius of 8.4 cm and volume of 3119.5 cm3. Give the approximate answer rounded to 2 decimal places.
Thank you!
Answer:
r=8.4cm
v=3119.5cmcube
volume of a cylinder
=pie r square height
pie=22/7
22/7×8.4×8.4×h=3119.5cm cube
221.76cmsquareh=3119.5cm cube
___________________________
221.76cm square(both sides)
h=14.07cm
The height of the cylinder is h = 14.09 cm
Given data:
To find the height of the cylinder, the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius, and h is the height.
Given that the radius is 8.4 cm and the volume is 3119.5 cm³, substitute these values into the formula and solve for h.
3119.5 cm³ = π(8.4 cm)²h
To isolate h, divide both sides of the equation by π(8.4 cm)²:
h = 3119.5 cm³ / (π(8.4 cm)²)
Now, calculate the approximate value of h as:
h ≈ 3119.5 / (π * 8.4²)
≈ 3119.5 / (3.14 * 70.56)
≈ 3119.5 / 221.1264
≈ 14.0989 cm
Hence , the height is 14.09 cm

Drew has two cats. One cat weighs 17 pounds, and the other one weighs 1212 pounds. Audrey’s dog weighs 33 pounds.
What is the difference in ounces between Audrey’s dog and the combined weights of Drew’s cats?
Enter your answer in the box.
Answer:
48 ounces.
Step-by-step explanation:
Steps:
Combine the weight of the cats.
12 (assuming it is a typo, 1212 pounds is a pretty big cat!) + 17 = 30 pounds
Convert to ounces.
33 pounds = 528 ounces
30 pounds = 480 ounces
Subtract the two/find the difference.
528 - 480 = 48.
The difference in ounces between Audrey's dog and the combined weights of Drew's cats is 48 ounces.

What’s is Arccsc .866 problem
Answer:
arccsc refers to "arc cosecant", or the radian measure of the arc on a circle corresponding to a given value of cosecant. Technical note: Since none of the six trig functions sine, cosine, tangent, cosecant, secant, and cotangent are one-to-one, their inverses are not functions.
what is arccsc equal to? The value of the arccsc function of any argument is an angle in radians whose cosecant function equals the given argument, that is, y = csc-1x if and only if x = cosec(y) for - /2 < y < /2 and y. ˗ˏˋ ❤︎ ࿐

51cm is the answer.
Step-by-step explanation:
a = ?
b = 68cm
c = 85cm
According to the Pythagoras theorem,
a² + b² = c²
a² + 68² = 85²
a² + 4624 = 7225
a² = 7225 - 4624
a² = 2601
a = 51cm
∴ the porch is 51cm tall.

11.25 or 11 1/4
Step-by-step explanation:
seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole
so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-
now we need the dimensions of each one-
rectangle one
l=5 w=2
rectangle two
l=5 w=1/4
now let us set up the equation and solve-
a=lw
rectangle one
a=5*2=10
rectangle two
a=5*1/4=1.25
and the last step is to add together the areas of both rectangles
10+1.25=11.25
and since you need your answer as a mixed number the answer is 11 1/4
(to do this you just put 11.25 over 100 and then simplify)
good luck :)

Which box plot shows data that is skewed right?
Answer:
I think its a
Step-by-step explanation:
The box plot in option A is right-skewed or in other words positively skewed.
A box plot is a graphical representation of the distribution of a dataset, particularly picturizing its center, spread, and potential outliers. It is also used to find the skewness in the distribution.
It is also known as a box-and-whisker plot.
The given data points are 10, 20, 30, 40, 50, 60.
As the number of observations, n = 6, is even, the following formula will be used to find the median:
[tex]Med(X) = \dfrac{X_\frac{n}{2}+X_\frac{n}{2} _+_1 }{2}[/tex],
where X is the random variable such that X ∈ [10, 60].
[tex]X_\frac{n}{2} = X_\frac{6}{2} = X_3 = 30\\X_\frac{n}{2}_+_1 = X_\frac{6}{2}_+_1 =X_{3+1} = X_4 = 40[/tex]
[tex]Med(X) = \dfrac{30 + 40 }{2}[/tex]
[tex]= \dfrac{70}{2} \\= 35[/tex]
It is clear that the whiskers of the box plot in Figure A are shifted right to the median, 35.
Thus, the box plot in option A is right-skewed.

24 swimmers are swimming in the pool. 9 of them are female. What fraction of swimmers are male?
Answer:
15/24 or 5/8
Step-by-step explanation:
Well 9 are female
The rest of the 24 has to be male so
24-9=15
15/24 or 5/8
The fraction of male swimmers is 5/8.
Given,
24 swimmers are swimming in the pool.
9 of them are female.
We need to find what fraction of male swimmers.
How do we find fraction of items from the total items?We write in two parts numerator and denominator.
= Numerator / Denominator
= Number of required items / Total number of items
Find the total number of swimmers.
= 24
Find the number of male swimmers.
= Total swimmers - Female swimmers
= 24 - 9
= 15
Find the fraction of male swimmers.
= Number of male swimmers / Total number of swimmers
= 15 / 24
Taking out the common factor
= 3 x 5 / 3 x 8
= 5/8
Thus the fraction of male swimmers is 5/8.

Step-by-step explanation:
Answer:

Step-by-step explanation:
Well the chance of picking 3 one time is 1/3
The chance of picking 3 the second time is 1/3
So at first, we've succeeded with probability 1/3 and failed with probability 2/3
We don't care what happens next if we've failed - we already failed.
So we've reached the "picking the second card with hope in our hearts" 1/3 of the time and we again succeed with 1/3 of a chance, so the total probability of success is 1/3 * 1/3 = 1/9
Think of the options:
3 and 3 - probability 1/3 * 1/3 = 1/9
3 and non-3 - probability 1/3 * 2/3 = 2/9
non-3 and 3 - probability 2/3 * 1/3 = 2/9
non-3 and non-3 - probability 2/3 * 2/3 = 4/9
Note that all the options sum to 1 - as probabilities of all options always should.

Which of the following is three dimensional and indefinitely large ?
Complete question is;
Which of the following is three-dimensional and infinitely large?
A. A solid
B. A line
C. A plane
D. Geometric space
Answer:
D. Geometric space
Step-by-step explanation:
The answer is option D.
A one dimensional object has only length, a two dimensional object has length and breadth, while a 3 dimensional object has length, breadth and depth.
Thus, a line is a one dimensional object because it has just length.
A plane is a two dimensional object.
While a solid and geometric space are both 3 dimensional objects.
However, solid is finitely large while geometric space is infinitely large.
