Question

if the ratio of circumference of two circle is5:3 what is the ratio of the radii​

Answer 1

Step-by-step explanation:

We know circumference of circle is 2πr.

2πr(Circle 1) ÷ 2πr(Circle 2) = 5 ÷ 3

$\frac{5(2\pi \: r)}{3(2\pi \: r)}$

Answer 2

Answer:

ur required answer ;-

let the radius of 1st circle = R and radius of 2nd circle = r

given.

the ratio of circumference of two circles = 5 : 3

to find , the ratio of radius = ?

as we know that

the circumference of circle = 2πr

the circumference of 1st circle / the circumference of 2nd circle

= 2πR/2πr

= R/r = 5/3

hence the ratio of the radius of two circles is 5:3.
