Question

# A Sphere, cylinder and a cone are of the same radius and same height . Find the ratio of their curved surface areas and their volumes?

Hint:

### Volume of sphere

Volume of cylinder

## The correct answer is: 4:2:√2

### Explanation:

- We have given A Sphere, cylinder and a cone are of the same radius and same height.
- We have to find the ratio of their curved surface areas and their volumes.

Step 1 of 1:

We have given a Sphere, cylinder and a cone are of the same radius and same height

Let that radius and height be r, h respectively.

Since, Sphere has equal radius and height.

So,

r = h

Then,

Volume of Sphere

Volume of cylinder

Volume of cone

Then Ratio of their volume will be

= 4:3:1

Step 2 of 2:

CSA of sphere

CSA of cylinder

CSA of cone

Then ratio of their CSA will be
