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

8 feet.

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.
