Question

find the ratio of the areas of two circle whose radii are 3 cm and 4 cm​

Answer 1

Step-by-step explanation:

if the ratio of radius of two circle is r1:r2

the the ratio of their area is (r1)²:(r2)²

a/q

ratio of their area = (r1/r2)²

= (3/4)²

= 9/16

hence the ratio of their area is 9:16
