Question

A circle has a circumference of 8 π meters.The radius of the circle is __ meters.

Answer 1

The radius is 4 meters

From the formula for the circumference of a circle, given as:

`C\text{ = 2}\pi r`

We solve for the radius as follows:

`\begin{gathered} C\text{ = 2}\pi r \\ 8\pi\text{ = 2}\pi r \\ r\text{ =}(8\pi)/(2\pi) \\ r\text{ = 4} \end{gathered}`

Therefore, the radius of the circle is 4 meters
