Flushing Meadows park has a very large circular pond as part of the center where their biggest attraction, the globe, is located. The pond needs to be renovated by summer. The pond is 400 feet wide. Draw a picture of this to aid in answering the questions below. Use the Math Toolbox to help you answer each of the questions below:

Area: r2 Circumference: 2πr OR πd Radius: d2 Diameter:2r

1a) If the designer measures the pond and determines that the length of the pond across is 400 feet wide, what is the length of the radius? Show your work.

b) The designer wants to plant new flowers around the pond. How many feet of flowers would she need to plant in this new design? Round to the nearest hundredth. Show your work.

c) The designer wants to determine how much water is covered on the surface once the pond is filled up. She claims that the area would be 160,000 square feet. Is she correct? Justify your answer showing work.
