Step-by-step explanation
the formula for the circumference is given by
![\begin{gathered} C=2\pi\text{ radius} \\ or \\ C=\pi\cdot\text{ diameter} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/zv754u1666tmimvicsay4gc5vkbv0sim6n.png)
so, to obtain the circumference, pi must be multiplied by diameter
Step 1
get the diameter of the circle:
The diameter is the length of the line through the center that touches two points on the edge of the circle.
therefore, the diameter of the circle is QS, so the answer is
