Question

A circular path is 2 feet wide while the inner diameter of 650 feet. How much farther is it around the outer edge of the path than around the inner edge? Round to nearest hundredth. Use 3.14 for π

Answer 1

Answer: 12.56

Step-by-step explanation:

The formula for perimeter of a circle is 2r”pi” or 3.14. The radius is just the diameter divided by 2. The area of the innermost circle is 2041. To find the outermost circle you add 2 to the radius, and then find the perimeter again. The perimeter is 2053.56. You simply subtract and you get 2053.56-2041=12.56.
