Question

the LSA of a cylinder is equal to the CSA of the cone if the radius be the same find the ratio of the height of the cylinder and slant height of the cone

Answer 1

Hey mate

Here's your answer__

Let the lateral surface area of cylinder be 2πr1h
curved surface area of cone =πr2l
Given:
2πr1h = πr2l
also r1 =r2
Therefore,
2h=l
h/l= 1/2.

Hope it helps☺
