Question

a bicycle wheel has a radius of 31.85cm. how far will the bicycle go if the wheel turns once?

Answer 1

circumference = diameter * π
diameter = radius * 2
diameter = 31,85 cm * 2
diameter = 63,70 cm
circumference= 63,70 * 3,14
circumference= 200 cm

If the wheel turns once, the bicycle goes 200 cm = 2m
