Question

The diameter of a bicycle wheel is 65cm.

How far does the bicycle go in 20 revolutions of the wheel

Answer 1

Recall that the circumference of a circle is equal to
C = pi*d
where d is the diameter.
First we get the circumference, then we multiply it by the number of revolutions, which is 20:
C = 3.14 * 65
C = 204.1 cm (this is only equal to 1 revolution)
Therefore, total distance travelled in after 20 revolutions is
204.1 * 20 = 4082 cm

Hope this helps~ :3

Answer 2

The diameter of a bicycle wheel is 65cm how far does the bicycle travel for each revolution of the wheel

Answer 3

Recall that the circumference of a circle is equal to C = πd, where d is the diameter.

Substituting the given value, we get:

C = π(65cm)
C = 204.1cm

This means that the bicycle covers a distance of 204.1 cm for each revolution of the wheel.
