Question

The circumference of a circle is 5 pi centimeters. What is the diameter?

Answer 1

The other person should be right

Answer 2

The circumference of a circle is given by the formula

`C=\pi D`

Where

`\begin{gathered} \pi\text{ is a constant} \\ D\text{ is the diameter of the circle} \end{gathered}`

To get the diameter of the circle, we will compare the given circumference with the formula to find the circumference of a circle

`C=\pi D=5\pi`

So, upon comparing

`\pi D\text{ with 5}\pi`
`\begin{gathered} \pi D=5\pi \\ \\ D=5 \end{gathered}`

Hence the diameter of the circle is 5 centimeters
