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
