Question

The radii of two circles are in the ratio 2:3. what is the ratio of their circumference . ​

Answer 1

Answer:

Step-by-step explanation:

Hi ,

Let r , R are radii of two circles ,

ratio of radii = 2 : 3

r /R = 2 / 3

ratio of their circumference = ( 2πr ) / ( 2πR )

= r / R

= 2 / 3

= 2 : 3

I hope this helps you.

:)

Answer 2

Answer:

2/3 = r/R

$2\pi \times r \div 2\pi \times r$

2/3=2:3
