A bicycle wheel has a diameter of 62cm. The wheel makes 80 complete
revolutions.
How far has the bicycle travelled?
Give your answer in metres

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:

[tex]C =2\pi r[/tex]

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:

[tex]C =2\pi \ 0.62[/tex]

[tex]C=3.8956\ m[/tex]

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

[tex]D=20*3.8956\ m[/tex]

D = 77.9 m

The bicycle traveled 77.9 m
