To find the circumference of a circle we use the formula

$c=2\cdot\pi\cdot r$

according to the circle ir has a radius of 35/2m.

Insert the data in the formula and use 22/7 as the approximation of pi

$\begin{gathered} c=2\cdot(22)/(7)\cdot(35)/(2)m \\ c=(22)/(7)\cdot35m \\ c=(770)/(7)m \\ c=110m \end{gathered}$
