At the park there is a pool shaped like a circle. A ring-shaped path goes around the pool. Its inner radius is 7yd and its outer radius is 11yd. 7yd 11yd We are going to give a new layer of coating to the path. If one gallon of coating can cover 4yd^2, how many gallons of coating do we need? Note that coating comes only by the gallon, so the number of gallons must be a whole number.
