Question

A circular rug has a radius of 2.5 feet. You want to sew fringe border around the rug. How many feet of fringe do you need to buy? Use π = 3.14 and round to one decimal place.

A. 15.7 feet
B. 7.9 feet
C. 31.4 feet
D. 25.0 feet

Answer 1

To find the amount of fringe needed, we can calculate the circumference of the circular rug using the formula C = 2πr. With a radius of 2.5 feet, the amount of fringe needed is 15.7 feet.

Step-by-step explanation:

To find the amount of fringe needed, we first need to calculate the circumference of the circular rug. The formula to find the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. In this case, the radius is 2.5 feet. Using π ≈ 3.14, we can calculate the circumference as follows:

C = 2πr = 2(3.14)(2.5) = 15.7 feet

Therefore, you would need to buy 15.7 feet of fringe.
