A round swimming pool has a circumference of 66 feet. Carlos wants to buy a rope to put across the diameter of the pool. the rope costs $0.45 per foot, and Carlos needs 4 more than the diameter of the pool. How much will Carlos pay for the rope and what is the diameter?

Circle circumference = pi * d

diameter then equals  circ/pi = 66/pi = 21 ft         + 4ft extra  = 25 feet   

 

25 feet x .45 $/ft = $ 11.25
