Answer 2

Answer:

Hope you can understand it easily. ...............

Step-by-step explanation:

Circumference of a circle=2πr

where,π = 22/7

,r = Radius of circle

Now,let the ratios be "X"

Now,circumference of the circle having ratio 3 will be=2×22/7×3X

=44/7×3X

=18.85

Now,circumference of the circle having ratio 5 will be=2×22/7×5X

=44/7x5X

=31.42

The,ratio of circumference will be=18.85:31:42

or,=132:220

or,=33:55

0r,=3:5(Ans)

Hence,If the ratio of radii of two circles is 3:5 the ratio of the circumference is 3:5.
