How many feet are traveled by a person riding once around the merry -go-round ? Clare says, " The radius of the merry -go-round is about 4 feet , so the distance around the edge is about 8π feet. " Andre says , " The diameter of the merry-go-round is about 4 feet, so the distance around the edge is about 4π feet."
The actual formula for the circumference is 2rpi. But the radius multiplied by 2 is the diameter. They are both right. Plug it the values in the formul and you will see. Sry if it doesn't make sense
