Question

The ares of two circle are in the ratio 16:25.find the ratio of their circumference.

Answer 1

Heyyyy mate..


Here is your answer...


given, areas of two circles= 16:25


area of first circle= 16

πr^²= 16

r= 4/π


area of second circle= πr^²= 25

r = 5/π


now circumference of circle= 2πr

2× π × 4/π = 8

and circumference of second circle= 2πr

2×π×5/π= 10


now ratio= 8/10= 4:5


hope it help you
