Question

If the area of two circles are in ratio 9 ratio 25 then find the ratio between their circumferences

Answer 1

Hey mate here is ur answer!!

let the area of one circle= A1

let the area of second circle= A2

A1/A2= 9/25

so,, pie r 1 squarw/ pie r2 squarw= 9/25

r1 square / r2 square= 9/25

so,,r1/r2= 3/5....(i)

now,,circumference of first circle / circumference of second circle= 2pie r1/ 2pie r2

so,,,it will become r1/r2 whose value is 3/5.

hence,,the ratio of their circumferences is 3:5.....

hope u understand...
