Just use the formula V = 1/3(πr²)h.
OpenStudy (anonymous):
Since diameter is radius doubled, d = 2r Since the diameter is 9, 9 = 2r 9 ÷ 2 = 2r ÷ 2 4.5 = r In this case, height is 5 times the radius, so h = 5r r = 4.5 h = 5(4.5) h = 22.5 Now that you have your values, just plug them into the formula that I gave you. You can figure out the rest. :)
