Answer 1

Step-by-step explanation:

As we know that,

Circumference of a circle =2πr

Whereas, r is the radius of circle.

Given:-

Radius of circle =20cm

Therefore,

Circumference of circle =2×3.14×20=125.6cm

Answer 2

Step-by-step explanation:

As we know,

Circumference =2pier

C = 2×3.14×20

C= 125.6

Circumference is 125.6
