Answer:
1. answer: 113.04 in
2. answer: 219.8 yd
3. answer: 276.32 ft
Explanation:
Using the formula to find the circumference of a circle, 2πr
1. Radius: 18 in. 2π multiplied by the radius, r is equal to 113.04.
2. The radius is half of the diameter, so dividing 70 in half gives 35. now that we have the radius, we can solve for the circumference. 2π(35) is equal to 219.8 yd
3. Radius: 44 ft, 2π multiplied by the radius, r is equal to 276.32 ft.
