Asked by Emily

A cylinder has a radius of 5 cm and a height of 12 cm. What would the might of a cone need to be if it has the sane volume and radius? Round to the nearest cm.

if you type in your question on google it will pull up some videos and other stuff right away, but i think the first video you see will be able to help you out

cylinder: pi r^2 h
cone: 1/3 pi r^2 h
if the volumes and radii are the same, then the cone would have to be 3 times as tall.
Answered by henry2,
pi*r^2*12 = pi*r^2*h/3.
Divide both sides by pi*r^2:
12 = h/3,
h = ---------cm. = Ht. of cone.
