The circular surface of a table has a diameter of 3 ft. What will cost to have the top refinished if the company charges $5 per square foot for the refinishing? Use 3.14 for π and round your answer to the nearest cent.

A = pi * r^2
A = 3.14 * 1.5^2
A = 3.14 * 2.25
A = 7.065 sq. feet
Cost = 5 * 7.065
