The Circumference of a Circle
Given a circle of radius r, the circumference, or the length of the complete arc of the circle is:
L = 2π r
The radius of the given circle is r=4 yd, thus the circumference is:
L = 2π (4 yd)
Using π=3.14:
L = 2*3.14 (4 yd)
L = 25.12 yd
The circumference of the circle is 25.12 yd
