The the ratio of circle circumference to the radius is always 2 π.
C = 2 r π
In this case:
C = 43.96
r = 7
also:
C = 2 r π
43.96 = 2 ∙ 7 ∙ π
43.96 / 7 = 6.28 = 2 π
A circle has a circumference of 43.96 cm and a radius of 7 cm.
What number represents the ratio of the circumference to the radius of this circle?
