Question

the ratio between the radii of two circle is 5 : 7 find the ratio between their circumference and areas ​

Answer 1

Answer:

The ratio of the circumference of the circle = 5 : 7

Let circumference of first ratio = 5x

∴ 2πr = 5x ⇒ r = 5x/2π

and the circumference of second ratio = 7x

∴ 2πr = 7x ⇒ r = 7x/2π

Ratio between their radii = 5x/2π: 7x/2π

= 5 : 7
