Question

Instructions: Find the circumference of the circle and round to the nearest tenth.

Answer 1

The circumference of the circle formula is

`C=2\pi r`
`r\rightarrow radius`
`\begin{gathered} diameter=7.8yd \\ r=(diameter)/(2)=(7.8)/(2)=3.9yd \\ \end{gathered}`
`\begin{gathered} C=2\pi r \\ C=2*\pi*3.9 \\ C=24.5yd \end{gathered}`

Hence, the circumference of the circle is 24,5yd
