Question

The lateral surface area ofa cylinder is equal to the curved surface area of a cone. If their
bases are the same, find the ratio of the height of the cylinder to the slant height of the cone

​

Answer 1

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's helps......
