Answer:
circumference = 12.56 m.
Step-by-step explanation:
circumference of a circle is the distance around the circle or the perimeter of the circle.
the diameter is two times the radius
d = 2 r
circumference = 2 π r = π (2r) = π d
Given: diameter = d = 4 and π = 3.14
∴ circumference = 4 * 3.14 = 12.56 m
