Answer 1

Explanation:

The circumference of a circular hot tub at a hotel is 56.5 yards what is the diameter of the hot tub

Answer 2

`\bf \textit{circumference of a circle}\\\\ C=2\pi r\qquad \begin{cases} r=radius\\ d=diameter\\ d=2r\\ -------\\ C=56.5 \end{cases}\implies 56.5=2\pi r\implies \cfrac{56.5}{2\pi }=r \\\\\\ d=2r\implies d=\underline{2}\cdot \cfrac{56.5}{\underline{2}\pi }\implies d=\cfrac{56.5}{\pi }`
