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
