Question

The radius of a circle is 3 inches long. what is the circumference?

Answer 1

Given:

a.) A circle with a radius of 3 inches long.

To be able to get the circumference of the circle, we will be using the following formula:

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

Where,

C = Circumference

r = radius

We get,

`\begin{gathered} \text{ C = 2}\pi r \\ \text{ = 2(3.14)(3)} \\ \text{ = 6 x 3.14} \end{gathered}`
`\text{ C = 18.84 in.}`

Therefore, the circumference of the circle is 18.84 in.
