Answer:

d = 2\sqrt{30}

Step-by-step explanation:

Given

Volume = 300\pi ft^3

Height =10ft

Required

The diameter

The volume of a cylinder is:

V = \pi r^2h

So, we have:

300\pi = \pi * r^2*10

Divide both sides by the common factors

30 = r^2

Take square roots of both sides

r = \sqrt{30}

The diameter is:

d=2r

So:

d = 2* \sqrt{30}

d = 2\sqrt{30}

or

d = 10.95
