Question

the radii of two circle are in the ratio 2:3. what is the ratio of their circumferences

Answer 1

Hey ..

This is your answer.

It is given that ratio of radii of circles is 2:3.
Let the radius of one circle be r₁
Radius of second circle = r₂
ATQ,  r₁/r₂ = 2/3

So, ratio of their circumference = 2πr₁/2πr₂
$= \frac{2 \pi 2}{2 \pi 3} = \frac{2}{3}$

Hence, the ratio of circumference = 2:3

Answer 2

Hey ..

This is your answer.

It is given that ratio of radii of circles is 2:3.

Radius of one circle = r1
Radius of second circle = r2
r1/r2 = 2/3
So, ratio of their circumference = 2πr1/2πr2
= 2π2/2π3 = 2/3

Ratio of circumference = 2:3
