Answer:

<em>The bicycle traveled 77.9 m</em>

Step-by-step explanation:

<u>Circumference of a Circle</u>

Given a circle of radius r, the circumference or perimeter is calculated as follows:

C =2\pi r

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:

C =2\pi \ 0.62

C=3.8956\ m

Given the wheel makes 80 complete revolutions, the total distance covered by the bicycle is:

D=20*3.8956\ m

D = 77.9 m

The bicycle traveled 77.9 m
