Question

How much water, in cubic feet, will a cylindrical tank with a radius of 12 feet and a height of 30 feet hold (use 3.14 for pi)?

Answer 1

Hint*
\[\large V = \pi r^2 h\]
Solve that for V with your given parameters r = 12 and h = 30 and pi = 3.14

Answer 3

John's suggested formula is precisely the right one to use here.
You are told that the radius of the vertical cylinder is r, and r = ?
You are told that the height is h, and that h = ?
substitute these values into John's equation. Also substitute 3.14 for pi.
Evaluate the volume, V.
