Find the area of a circle with Radius 8 yd.
Use the value 3.14 forn, and do not round your answer.
Answer:
[tex]64\pi yd^{2}[/tex] or 201.062 [tex]yd^{2}[/tex]

Area of a circle: [tex]\pi r^{2}[/tex]
Given:
r=8 yd
[tex]\pi[/tex]=3.14
[tex]\pi (8^{2})=64\pi[/tex]
=201.062 [tex]yd^{2}[/tex]
I hope this is correct and helps!
1- the diameter of a CD is 24 cm nearest to cm .find its upper and lower bound.
2- if your mass is 57g .your mass could actually be anything between 56.5kg and 57.5kg.do you agree or not explain the reason .why?
3- write 7.875 nearest to a two decimal place.
4- write 2.3242900000 nearest to a two decimal place.
5-divide 180 kd between ahmed ,jasim and Dalal in the ratio of 3:1:5.
answer any one of this questions
Answer:
1) Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) I disagree
3) 7.88
4) 2.32
5) Ahmed = 60 kg
Jasim = 20 kg
Dalal = 100 kg
Step-by-step explanation:
1) diameter = 24 cm was rounded up to the nearest cm.
Now, usually, we round up 0.5 to the next whole number. This means that, the actual diameter is;
23.5 ≤ D < 24.5
Thus;
Lower bound = 23.5 cm
Upper bound = 24.5 cm
2) If you weigh 57g,converting to kg is 0.57 kg.
Now, this does not fall in between 56.5kg and 57.5kg given.
Thus, I disagree that your weight could be anything between 56.5kg and 57.5kg .
3) 7.875 approximated to the nearest two decimal place = 7.88
4) 2.3242900000 to the nearest 2 decimal place = 2.32
5) 180 kd shared between ahmed ,jasim and Dalal in the ratio of 3:1:5.
Total part of ratio = 3 + 1 + 5 = 9
Their respective shares are;
Ahmed = 3/9 × 180 = 60 kg
Jasim = 1/9 × 180 = 20 kg
Dalal = 5/9 × 180 = 100 kg

Answer:
Step-by-step explanation:
m/g=3/4
m=3g/4, now we can express m in terms of g
g=4+m, using m found above in this equation gives you
g=4+(3g)/4
4g=16+3g
g=16, since m=3g/4
m=3(16)/4
m=48/4
m=12
So total cupcakes sold is 12+16=38.
38 cupcakes were sold.

A television screen is a rectangle 44 inches wide and 24 inches long. A television size is advertised as the length of its diagonal. What is the size of the television? In other words, what is the length of the diagonal? Round your answer to the nearest hundredth.
Answer:
50 inches Approx
Step-by-step explanation:
GIven data
Width= 44in
Length= 24in
Diagonal=???
We know that the expression for the diagonal is given as
D^2= W^2+L^2
substitute
D^2= 44^2+24^2
D^2= 1936+576
D^2= 2512
D=√2512
D= 50.11
Hence the size of the TV is 50 inches Approx
Find the perimeter of ABCD please.
Answer:
Perimeter = 71
Step-by-step explanation:
angles formed by tangent lines has equal side lengths.
segments from A to tangent point = 17 each
segments from B to tangent point = 12 each (29 - 17 = 12)
segments from C to tangent point = 2.5 each
segments from D to tangent point = 4 each (21 - 17 = 4)
Perimeter = 2(17) + 2(12) + 2(2.5) + 2(4) = 71
Solve to find the answer of blue pills Mr body took: number of blue pills, b, mr mattics give him was 3 more than the number of green pills,g, total number of pills took was 17, 11 blue pills to kill
Answer:
Mr body took 9 blue pills
Step-by-step explanation:
Total number of pills consumed = 17
Number of blue pills, b = 11
Number of blue pills, b = g + 3
So that,
b = g + 3
11 = g + 3
g = 8
Total number of pills recommended = b + g
= 11 + 8
= 19
Total number of pills consumed = 17
Thus,
Number of blue pills consumed = 17 - 8
= 9
Therefore, Mr body took 9 blue pills.

Answer:
h = 36.75 feet
Step-by-step explanation:
h(t) = - 3t² + 15t + 18
x - coordinate of vertex is ( - [tex]\frac{b}{2a}[/tex] )
t = - 15 ÷ [ 2( - 3 )] = 2.5 seconds
h(t) = - 3(2.5)² + 15(2.5) + 18 = 36.75 feet

A zoo is located on a rectangular area of land the length of the rectangular is 2 1/4 miles the width of the rectangular is 1 1/2 miles what is the total area of the zoo
Answer:
area = 3 3/8 miles²
Step-by-step explanation:
Width = 1.5
Length = 2.25
2.25 x 1.5 = 3.375 miles²
another way:
1 1/2 x 2 1/4 = 3/2 x 9/4 = 27/8 = 3 3/8 miles²
A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building?
Answer:
height = 28 feet
Step-by-step explanation:
using the Pythagorean theorem:
height = 35² - 21²
height² = 1225 - 441 = 784
height = 28 feet

Find the value of x.
Question options:
A)
35.631
B)
49.508
C)
86.113
D)
20.485
Step-by-step explanation:
[tex] \tan(26) = \frac{42}{x} \\0.487732588565 \times x = 42 \\ x = 86.11276134633[/tex]
C.x=86.113
Answer:
C (86.113)
Step-by-step explanation:
First, find the missing angle B. Since angles in a triangle add upp to 180,
180-26-90= 64
Then use the formula a/sina = b/sinb
' a' in the formula is the missing length X and sina is the corresponding(opposite) angle of X which is sin64.
B in the formula would be 42 and sinb is sin26 (the angle).
Substitute all values into the formula,
X/sin64 = 42/ sin26
Shift sin64 to the right side:
X= 42(sin64)/ sin26
X= 86.113
Hope this makes sense:)
