Solving for A variable......

 ln{[(5280×(236674+30303×√61))³ +744]² − 393768} ÷ sqrt(A)= π

Multiply both sides by sqrt(A)   ....

 ln{[(5280×(236674+30303×√61))³ +744]² − 393768} = sqrt(A)* π

Divide both sides by  π

 ln{[(5280×(236674+30303×√61))³ +744]² − 393768} *π    =  sqrt(A)

Square  both sides

 [ ln{[(5280×(236674+30303×√61))³ +744]² − 393768} *π ] ^2    =   A

Thank you CPhill. I was looking for a numerical value of "A". I'm having some problem getting the right answer. It is supposed to be a whole integer.

Oh, OK....let's see....

WolframAlpha evaluates "A" in the original equation as   ≈ 1708
