Sam is planning to put a fence around a circular garden in his lawn. The garden is 10 feet from end to end.

If the total cost of a fence is \$440, what is the unit price of fence per foot? (Use ð=227.)

1. I generally don't think of circles as having ends, so maybe the fence is rectangular or square.

However, since you talk about using pi=22/7, I'll assume you want a circular fence, and the diameter is 10 ft.

So, C = 10pi = 31.4 ft

\$440/31.4ft = \$14.01/ft

8. Luke is going to repaint both sides of the door of his room. The door is 36 inches long by 80 inches high. His options at the paint store are below.

1 gallon of paint costs \$10 and covers 4,400 square inches of area.

12 gallon of paint costs \$7 and covers 2,200 square inches of area.

If the door requires 2 coats of paint, what is the minimum cost of painting the door of Luke's room?
