Julia and Cody are planning a garden. Julia said if they make the garden round it would look better. Cody said if they make the garden square they will be able to plant more. They have enough space to make a round garden with a diameter of seventeen feet or a square garden with each side being seventeen feet. If they put three plants in each square foot of ground, how many more plants will they be able to plant in the square garden than they could plant in the round garden?
