A circular coffee table has a diameter of 5 ft. What will it cost to have the top refinished if the company charges $3 per square foot for the refinishing?
First, find the circumference of the circle with diameter 5 feet.
We use this formula:
C = pi x d, where pi = 3.14 and d = 5 feet
C = 3.14 x 5 feet
C = 15.7 feet
Now multiply 15.7 feet by $3 and you will find how much it will cost to have the top refinished.
Can you finish?
