Question

8. The circumferences of two circles are in the ratio 1:3. Find the ratio of their Areas​

Answer 1

Solution

Answer:-

9:1

Given

circumferences of two circles are in the ratio 1:3

To find

Ratio of their areas

Explanation

Let us radius of two circles be m and n

2πm: 2πn= 3:1

Hence, m:n = 3:1

Ratio of areas of circles will be,

2πm²:2πn²= m²:n²= 9:1

Hence, Ratio of their areas is 9:1
