Question

If the radii of 2 circle are given in ratio 3ratio 4 then the ratio if their area is

Answer 1

Step-by-step explanation:

Hey mate here is your answer:

let the radius of first circle be 3x and of the second circle be 4x

now area of 1st circle = πr^2 = π(3x)^2 = 9πx^2

area of 2nd circle = πr^2 = π(4x)^2= 16πx^2

now ratio of area will be 9πx^2/16πx^2 = 9/16 =9:16
