The formula for calculating the radius of a circle given its diameter is radius equals diameter divided by two. Using the information given of a circle with a diameter of four, the radius is four divided by two, or two.

By definition we have the relationship between the diameter of a circle and its radius is as follows:
r = d / 2
where
r: radio
d: diameter
Since the diameter of the circle is 4, then the radius will be given by
r = (4) / 2 = 2
answer
the radius of the circle is 2 units.
