All of the centra angles in a regular polygon must add up to 360 degrees. Also, because you're told that it is a regular polygon, the "regular" indicates that all of the central angles will be the same. Divide 360 degrees by 18 degrees to get the number of central angles, which is the same as the number of sides. 360/18 = 20. Therefore, the polygon has 20 sides. Hope that helps!

Remember the formula of the area of a circle is:
SO given that
V = 226.98
and
Plug in a chug
226.98 = 3.14 *
r = 8.50
Remember that d = 2 * r
d = 2 * 8.5 = 17
