Question

A hemisphere and cone stand on equal bases with equal heights. Find ratio of their curved surface areas​

Answer 1

Step-by-step explanation:

A cone hemisphere and a cylinder stand on the same ... equal height find the ratio of their curved surface area - 1140432 .

Answer 2

Curved surface area of cone =
