Answer 1

Explanation:

We have given that,

The inner radius of a bicycle wheel is 12 inches.

It is required to find the expression to find the inside circumference of this wheel.

The outer surface of the wheel is equal to its circumference. It is given by :

`C=2\pi r`

r is radius of wheel

`C=2* 3.14* 12\\\\C=75.36\ \text{inches}`

This is the required explanation.
