well, let's recall that the diameter is twice as long as the radius, let's find the radius firstly then,

[tex]\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\ -----\\ A=94\pi \end{cases}\implies 94\pi =\pi r^2\implies \cfrac{94\pi }{\pi }=r^2 \\\\\\ 94=r^2\implies \sqrt{94}=r\\\\ -------------------------------\\\\ \textit{so the diameter is twice as much}\qquad 2\sqrt{94}[/tex]

sadly, the one above is only for a circle with 94π as area, not for 94 pie, but yours sounds more delicious.
