At the park there is a pool shaped like a circle with diameter 20yd. A ring-shaped path goes around the pool. Its width is 5 yd. 20 yd We are going to give a new layer of coating to the path. If one gallon of coating can cover 4 yd 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. (Use the value 3.14 for TT)
