Question

A circle has a circumference of 50.24 units. What is the radius of the circle?

Answer 1

8 units

Explanation:

Formula to find the circumference of a circle: 2 π r= π d (2 pie r = pie d)

First substitute the circumference, then solve for radius

50.24 = 2 π r

50.24 ≈ 2(3.14)r

8 ≈ r

Thus the radius is approximately 8 unit.

Hope this helps! :)

Answer 2

8 units

Explanation:

The circumference of a circle is given by

C = 2*pi*r

50.24 = 2 * 3.14 *r

50.24 = 6.28 r

Divide each side by 6.28

50.24/6.28 = 6.28r/6.28

8 =r
