A circle has the diameter of 8, what is the Radius of the circle?

r = 4

Step-by-step explanation:

The radius is always half the length of the diameter. In this case r = 4.

4 units

Step-by-step explanation:

The diameter is the measure from one edge of the circle to the other. The radius is the measure from the center of the circle to the edge.

Therefore, the radius is half of the diameter.

r=d/2

The circle has a diameter of 8 units. Substitute 8 in for d.

r=8/2

Divide

r=4

The radius of the circle is 4 units
