The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7

Here are your equations:
r = diameter/2
C = 2*pi*r

Now all you have to do is plug in the 4.75 for the diameter, and you have your answer!
If you don't have a calculator with "pi" on it, use 3.14159.
