Question

A bicycle wheel has a diameter of 62cm. The wheel makes 80 complete

Answer 1

Answer:

The bicycle traveled 77.9 m

Step-by-step explanation:

Circumference of a Circle

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
