Question

7. A cylindrical tank can hold 2279.64 cubic feet of water. The radius of the tank is 11 feet. What is the height of the tank?

Answer 1

r = 8.12

Explanation:

The volume for a cylinder is V=πr^2h therefore,

v = 2279.64

h = 11ft

r = ?

2279.64 = πr^2 * 11

`(2279.64)/(11)= {\pi r^2} \\`

207.24 = πr^2

`(207.24)/(\pi) =r^2\\\\66 = r^2\\\\√(66) = r\\\\\\8.12 = r`
