The area of a circle is the radius squared x pi.
Area = r^2 x pi
R is the radius which is half the diameter.
Diameter = 102 inches
Radius = 102/2 = 51 inches
Area = 51^2 x pi
Area = 2,601pi inches^2 ( in terms of pi) or
Area = 8,167.14 inches^2
It costs her $48.10 to get 13 gallons of gas
Answer:
1071.8 to 1 decimal point
Step-by-step explanation:
The first thing you would do is multiply the 4/3, 3.14 and the 8^3
So we know that 8^3 is 8X8X8 which is 512
So the first thing you do I 4/3 X 3.14 X 512 = 160768/75 (2143.6 1DP)
Then you would divide this by 2
2143.6/2 = 1071.8
