    \bf \textit{circumference of a circle}\\\\ C=2\pi r\quad  \begin{cases} r=radius\\ -----\\ C=28.26 \end{cases}\implies 28.26=2\pi r\implies \cfrac{28.26}{2\pi }=r \\\\\\ \cfrac{14.13}{\pi } =r

    now, that’s just the radius, recall the radius is half the diameter, so the diameter is twice as much as the radius, so the diameter is two times that much.
