How do you simplify, differentiate, set equal to 0, and solve for x the equation 2x(30-πx-2x)/2 +(1/2)πx^2?
Update:
Area = A = 2xh + (1/2)πx^2
= 2x(30 - πx - 2x)/2 + (1/2)πx^2
simplify a bit, then differentiate,
set the derivative equal to zero and solve for x

I can't do anything to that "equation", because it's not an equation. Equations have equals signs, and there is no equals sign in your question.
