Question

A circle has a circumference of 87 meters. What is the radius of the circle?
4 m
8 m
16 m
2 m

Answer 1

Step-by-step explanation:

Since the circumference is equal to 2pi times the radius, it follows that the radius is the circumference divided by 2pi.

This means that for this problem, the radius is 87/(2pi), which is about 16m.
