Question

• The
ratio of
areas of two wheels is 25:49
Find the ratio of their radii​

Answer 1

Answer:

5:7

Step-by-step explanation:

25:49

There is ratio of the areas of 2 wheels

There radii radio =

5:9

Answer 2

Lets r1^2 and r2^2 be the two radii resp.

By the question,

25/49=Pie×r1^2/pie×r2^2

r1/r2=root over 25/root over 49

r1/r2=5/7

Therfore,the ratio of the radii is 5:7

Plzz mark me brainiest if it helps :))
