Question

A circle has a circumference of 10 inches. What is the radius of the circle?

Answer 1

The formula for finding the radius of a circle while only knowing the circumference is r=C ÷ 2π. Substituting the value 10 for C, and 3.14 for π, we get:

r=10 ÷ 3.14 · 2         Now we divide 10 by 6.28
r≈1.59

Answer 2

1.59 is the radius of the circle
