Scott wants to buy fencing to place around a semicircular rock garden. The diameter of the semicircle is 16 feet long. Using 3.14 for π, he calculates that he needs to buy about 25.12 feet of fencing. The fencing is sold by the foot, so he plans to buy 26 feet of fencing. Explain why Scott's thinking is incorrect, and find the correct amount of fencing he should buy.
