Given:

Diameter of a circle  = 5 meters

Find the Circumference of the Circle.

Formula for the Circumference of Circle: c = 2πr

diameter  = 2r

r = d/2

r = 5/2

r = 2.5

Solution:

Substitute the value of r in the given formula for the circumference of the circle.

c = 2πr

c = 2π(2.5)

Circumference = 15.71 meters
