consider two circular ferris wheels. Ferris wheel A has a radius of 7.5 feet, and wheel B has a diameter of 180 inches. Which Ferris wheel has a greater circumference
if ferris wheel A has a radius of 7.5ft=90in which you would multiplied by 2 which give a diameter of 180in and ferris wheel B has a diameter of 180in they would have the same circumference.
