The diameter of a table is 5 feet. What is the circumference

1 answer:

6 0

if the diameter is 5, then its radius is half that, or 2.5.

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2.5 \end{cases}\implies C=2\pi (2.5)\implies C=5\pi \implies C\approx 15.71$
