Question

Find the circumference of the circle. Use 3.14 for π. Round to the nearest hundredth, if necessary.The circumference of the circle is about___________ feet.

Answer 1

The formula to calculate the circumference (C) of a circle is,

`C=\pi D`

Given:

`\begin{gathered} D=\text{Diameter}=23ft \\ \pi=3.14 \end{gathered}`

Therefore,

`\begin{gathered} C=3.14*23ft=72.22ft \\ \therefore C=72.22ft \end{gathered}`

Hence, the circumference is about 72.22ft.
