Question

the ratio of circumference of two circles is 5 ratio 3 what is the ratio of their radii

Answer 1

Answer:5:3

Step-by-step explanation: circumference of a circle is 2(pi)r

Let one of the radius of circle be R and other be r.

2 pi R : 2pi r=5:3

R:r=5:3 because 2 pi gets cancelled.

Answer 2

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
