<u>Circumference of a Circle</u>
Given a circle of radius r, the circumference or perimeter is calculated as follows:
The radius of the bicycle wheel has a radius of r=62 cm. Converting to meters r=62/100=0.62 m.
Calculate the circumference:
Given the wheel makes 80 complete revolutions, the total distance covered by the bicycle is:
D = 77.9 m
The bicycle traveled 77.9 m
Given :
