Using the equation of the perimeter of a circle to find the diameter, we have:
[tex]\begin{gathered} P=\pi\cdot D\text{ (P: perimeter, D: diameter}) \\ 94.2=(3.14)D\text{ (Replacing the values)} \\ 30=D(\text{Dividing by 3.14 on both sides of the equation)} \\ \text{The answer is }30\text{ inches.} \end{gathered}[/tex]
