Question

the radii of two circles are in the ratio 2 is to 3 what is the ratio of their circumferences ​

Answer 1

Answer:

Step-by-step explanation

Ans is 2 is to 3 as 2πr1/2πr2 = r1/r2 = 2/3

Answer 2

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
