Question

The ratio of radii of two circles is 3:4, find the ratio of their areas.
​

Answer 1

Step-by-step explanation:

See in this question, ratios can be written in fraction form so ratio r1 and r2

We have to find the ratio of areas so, a1 ans a2 and their formulas and in the formula mention r1 and r2 like we did above then π and π will cancel out and height and height will can out leaving you with r1^2 and r2^2 which is 3^2 and 4^2 that is 9 and 16. Hope it helps! Please mark me as the brainliest!

Answer 2

Step-by-step explanation:

Let radius of first circle be 3x and the second one be 4x.

Ratio of their radii= 22/7 × 3x × 3x : 22/7× 4x × 4x

= 3x × 3x: 4x × 4x
