CITY PLANNING

A city is planning a circular duck pond for a new park. The depth of the pond will be 4 ft. Because of water resources, the maximum volume will be 20,000 ft3. Find the radius of the pond. Use the equation V=πr2h, where V is the volume, r is the radius, and h is the depth.

Solve 4x2 – 100 = - 100

Solve x2 – 9 = 16
