#4# inches

#8/2 = 4#
because #d = 2r#

where:
#d# = diameter
#r# = radius

The radius of the circle is #4# inches.

Diameter means twice a radius, as you can see here:

Since the diameter is #8# inches, then we can do #8/2# to find the radius, or #4# inches.

The radius of the circle is #4# inches.
