If the ratio of two circles is 16:25 , find the ratio of their circumference

TooFree: What is the ratio of the two circles 16 : 25 based on ? The radius or the area?

kalanamala: tell me the process

TooFree: No, I am trying to clarify your question .. you must have missed a word in your question:

TooFree: the ratio of "radius" of two circles is 16:25 or If the ratio "area:" of two circles is 16:25?

Answer:

The answer is 4:5

Step-by-step explanation:

Let r and R are radii of two circles ,

Ratio of their areas = 16 : 25

πr² : πR² = 16 : 25

r² / R² = ( 4/5 )²

r / R = 4/5-----( 1 )

Ratio of circumferences = 2πr / 2πR

= r / R

= 4/5

[ From equation ( 1 ) ]

= 4 : 5

I hope this helps you.
