Question

The lengths of two radii of two cones is 3:5 What is the ratio of its surface area?

Answer 1

Step 1:

In this question, we are given the following:

The lengths of two radii of two cones is 3:5 .

What is the ratio of its surface area?

Step 2:

The details of the solution:

Since the lengths of two radii of two cones is 3 : 5 , the ratio of the surface area will be:

`(\text{ 3 \rparen}^2:\text{ \lparen5 \rparen}^2\text{= 9 : 25}`

CONCLUSION:

The ratio of its surface area = 9 : 25
