Enter the Radius


Circumference of a circle radius 20 centimeters is 125.6 centimeters.

Circumference of a circle is the length of the boundary of the circle. If we cut open the circle and straighten it the length of the boundary will be the measure of the circumference of the circle. Circumference of a circle radius 20 centimeters is 125.6 centimeters.

Circumference of a Circle side 20 cm is 125.6 cm

Steps:

Given that Radius, r = 20 cm

We know that, Circumference of a circle= 2πr

Put the value of radius value in Circumference Formula.

Circumference = 2π x 20 cm

Substituting the value of π

Circumference = 2 x 3.14 x 20

Circumference = 125.6 cm

∴ Circumference of a Circle side 20 cm is 125.6 cm
