c = d*pi
88 = 22/7 * d
d = 88 / (22/7)
d = 28
r = d/2
r = 14

The formula for the circumference of a circle is π × diameter. We can find the diameter first by dividing 88 by 22/7 (because we're using that instead of π) and we get 28. If 28 is the diameter, then the radius is half of that value, which is 14. I hope this helps!
