Answer:
20
Step-by-step explanation:
The area of a circle is equal to pi*radius^2
We can then write this as
314.1592=π*r^2
We then divide pi to get
100=r^2
take the square root and you find that the radius equals around 10
The diameter is always equal to the radius times two which means that the diameter is 20
hope this helps
Answer:
Step-by-step explanation:
We are told that the perimeter is 48 = 2L + 2W. This reduces to
24 = L + W. Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:
a) If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm
b) If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm
c) If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm
Answer:
B. 27.5
Step-by-step explanation:
1/2 (b x h)
B (Base) = 11
H (Height) = 5
1/2 (11 x 5)= 27.5
Answer:
2054
Step-by-step explanation:
The equation for the growth of people = 308.7(1097)^x
The equation for the growth of vehicles = 246(1155)^x
If the number of both are equal tham
308.7(1097)^x=246(1155)^x
Dividing both sides by 246
1.254878(1097)^x=(1155)^x
Dividing both sides by (1097)^x
1.254878=(1155÷1097)^x
X=4.406 decades
X=44 years
145 divided by 7 =20.71
