Question

The radius of two circles are in the ratio of 3:1 what will be ratio between their areas

Answer 1

Heya, here is your Answer :-

let radius of First circle be 3x and second circle be x.

Then,

Area of First circle = πr^2 = π*9x^2 square units

Area of Second circle = πr^2 = π*x^2 square units

Required Ratio = π*9x^2 : π*x^2 = 9 : 1

So,
Required Ratio = 9 : 1
