Asked by Christine

Please help..not wanting answer just where to start... A cylinder has a radius of 5 centimeters and a height of 12 centimeters. What would the height of a cone need to be if it is the same volume and radius?
Answered by Reiny
volume of cylinder = π(5^2)(12) = ...

volume of cone = (1/3)πr^2 h

solve (1/3)π(5^2)h = π(5^2)(12)

after getting your answer it should be obvious why it is so.
