The diameter of a wheel is 50ft how do i find the distance around it 8 times?

The distance around any object is called its perimeter. The perimeter of a circle has a specific formula: 2(pi)r where pi is a number that is approximately 3.14 and r represents the circle's radius. In this case we are given the circle's diameter, however remember that the diameter of a circle equals two times its radius. So if: d = 50' and d = 2r Then r = 25' Now plus this radius into or equation to get: 2(3.14)(25) = 157' To get the distance around this circle 8 times, multiply the perimeter by 8: 157' * 8 = 1,256 feet
