Question

The radius of a circular car tire is 12.5 inches. Find the circumference. Use 3.14 for
`\pi`

Answer 1

78.5 in

Step-by-step explanation:

The circumference can be calculated as:

`C=2\pi\cdot r`

Where r is the radius and π is approximately 3.14.

So, replacing r by 12.5 inches, we get:

`\begin{gathered} C=2(3.14)(12.5\text{ in)} \\ C=78.5\text{ in} \end{gathered}`

Therefore, the circumference is 78.5 in
