CIRCLE PROBLEM:
How much water can hold a kiddie pool with a 6 foot diameter when filled 1 foot high?
The surface area of the circular base, in square feet can be calculated by the formula
area=pi%2Ar%5E2 with r=3= radius, measured in feet (half the diameter)
area=3.14%2A3%5E2=3.14%2A9=28.3 square feet (rounding pi and the result).
So we can fill the pool to 1 foot high with 28.3 cubic feet of water.

TRAPEZOID PROBLEM:
A lot has a 40 foot front on one street, with perpendicular sides measuring 70 and 50 feet, and backing to another street. What is the surface area of the lot in square feet?

area=%28base%5B1%5D%2Bbase%5B2%5D%29%2Aheight%2F2 area=%2870ft%2B50ft%29%2A40%2F2=2400ft%5E2
