Answer:
Pi is the circumference of (distance around) a circle divided by it diameter (largest distance across). The radius is one-half of the diameter. 2 pi radius means two times pi times the radius or 2 x pi x radius.
You can multiply in any order so this is the same as 2 x radius x pi.
2 x radius = diameter
diameter x pi = circumference (distance around)
2 pi radius is the circumference of a circle
You can multiply in any order so this is the same as 2 x radius x pi.
2 x radius = diameter
diameter x pi = circumference (distance around)
2 pi radius is the circumference of a circle
