Peter is making a circular flower bed that is 5 feet in diameter. He wants to place flexible edging around it. How many feet of edging does he need?
Use 3.14 for pi.
Round your answer to the nearest foot.
The circumference of a circle is given by the formula C = πd, where d is the diameter of the circle. In this case, the diameter is 5 feet, so the circumference is C = 3.14 * 5 = 15.7 feet.
Therefore, Peter needs approximately 15.7 feet of edging. Rounded to the nearest foot, he needs 16 feet of edging. Answer: \boxed{16}.
