Question

If the diameter of two circles are in ratio 2:3 then find its area

Answer 1

this is required answer

Answer 2

Let the diameters are 2x and 3x

So their radius will be R1 = 2x/ 2 = x

R2 = 3x/2

Area is given by = pi * r^2

A1 = pi * R1^2

= pi * x^2

A2 = pi * R2^2

= pi * (3x / 2)^2

= pi * 9x^2/4
