Step-by-step explanation:
+4 on both sides
-17 both sides
Divide by 20 both sides.
5/8 of them are not white, so 5/8 times 56, you get 35.
The circumference should be 37.68 because area= pi *r^2. So if area=pi*36, then the radius must be 6 which makes the diameter 12 and circumference=pi*diameter and 3.14*12= 37.68. So circumference of the circle is 37.68!
