问题
John is building a circular fence around his circular pool. The pool is 26 feet in diameter. If John wants to have 2 feet of space between the edge of the pool and the fence, what is the area that will be encompassed by the fence? (π=3.14)
选项
答案
If the pool has a diameter of 26 feet, and the fence needs to be 2 feet away from the edge of the pool, the diameter of the area enclosed by the fence would be 26+2+2=30 feet. Draw a picture to help visualize the problem: [*] The area of a circle is πr2. The radius is half of the diameter, so r=15. Substitute 15 for r and 3.14 for π and solve: Area=(3.14)(15)2 Area=706.5 ft2
