Circumference of a Circle side 4 cm is 25.12 cm
Steps:
Given that Radius, r = 4 cm
We know that, Circumference of a circle= 2πr
Put the value of radius value in Circumference Formula.
Circumference = 2π x 4 cm
Substituting the value of π
Circumference = 2 x 3.14 x 4
Circumference = 25.12 cm
∴ Circumference of a Circle side 4 cm is 25.12 cm
