Question

Find the circumference of this circleusing 3 for π.13C ~ [?]C = 2πr

Answer 1

The formula for the circumference of a circle is:

`C=2\pi r`

Where r is the radius of the circle.

The radius is given to be 13 and we want to use 3 for π, so:

`\begin{gathered} C\approx2\cdot3\cdot13 \\ C\approx2\cdot39 \\ C\approx78 \end{gathered}`
