13 pts.

Answer 1

circumference = 12.56 m.

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
