What is the radius of circle C?
The radius of circle C is _____ units

Answer 1

7 units

Explanation:

Radius is the same as saying diameter divided by 2. 14 divided by 2 = 7, so the radius is 7 units.

Answer 2

The radius = 7 units

Explanation:

The diameter of a circle is twice the radius

d = 2r

If d =14 units

14 = 2r

Divide each side by 2

14/2 = 2r/2

7 =r

The radius = 7 units
