Your friends can move 20 boxes an hour, but they require one 16 inch (diameter) pizza for this work. Write a function in Python that takes the number of boxes you have and returns how much square feet of pizza you will have to buy. Use the function header:
sqFtPizza(numBoxes)
and have it return the square feet of pizza as a float. Assume that the pizzas are perfectly round and that your friends require a full pizza even if they only work a partial hour. (In case you've forgotten your geometry, the area of a circle is pi*r^2. Use 3.14159 for pi.)
