Question

Q1. If the ratio of the radii of two circles is 2:3, find the ratio of their areas​

Answer 1

Answer:

ration of the radii of two circles is2:3

the ratio of their areas,

2:3

2= 4

3=9then,

4:9

Answer 2

Answer:

Let’s consider the radius of two circles C1 and C2 be r1 and r2. We know that, Circumference of a circle (C) = 2πr And their circumference will be 2πr1 and 2πr2. So, their ratio is = r1: r2 Given, circumference of two circles is in a ratio of 2: 3 r1: r2 = 2: 3 Then, the ratios of their areas is given as = 4949 Hence, ratio of their areas = 4: 9. mark it as brainlist
