Question

The ratio of circumferences of two circles is 5: 3. What is the ratio of their radii ?​

Answer 1

Given :

• Ratio of the circumference of circle is 5 : 3

______________________________

To Find :

• Ratio of radii

______________________________

Solution :

We know that

★ Circumference of circle = 2πr

➤ Let the radii be R and r

→ 5/3 = 2πR/2πr

→ 5/3 = πR/πr

→ 5/3 = R/r

∴ The ratio of their radii is 5:3
