Question

12. A car tire has a circumference of 46 inches. Find the radius of the tire.Round to the nearest tenth. I

Answer 1

we have the following:

`\begin{gathered} c=2\cdot\pi\cdot r \\ r=(c)/(2\cdot\pi) \end{gathered}`

replacing, c = 46 inches:

`\begin{gathered} r=(46)/(2\cdot3.14) \\ r=7.32 \end{gathered}`

therefore, the radius is 7.32 inches
