Question

The circumference of two circles are in the ratio 8is to 6 find the ratio of their areas
​

Answer 1

Answer:

thitha apon me 360 multiple 2πr

Answer 2

Answer:

let circumferencebe C and c

and area be A and a

given that

C:c =8:6

so

C:c=2πR:2πr=8:6

here 2π cancle out after that R:r=8:6

area will be

A:a=πR^2:πr^2=?

here π is cancel out

so A:a= R^2:r^2= 8^2:6^2

A:a= 64:36

or A:a= 16:9
