Question

cylinder has a height of 7 feet. Its volume is 1,406.72 cubic feet. What is the radius of the cylinder?

Answer 1

Answer:

8 feet.

Step-by-step explanation:

The formula for volume of a cylinder is $r^{2} \pi h$ (using 3.14 for $\pi$). So it would be $r^{2}$ times 7 times 3.14 which equals $r^{2}$ times 21.98. 1406.72 divided by 21.98 is 64. The square root of 64 is 8. The radius is 8.
