Calculate the volume of revolution generated by the function, f(x) = (3^x)√x, for the domain x = [0, 1]

First we recall the general formula for the volume of revolution: V = π ∫ [f(x)]² dx Substituting our function, this gives: V = π ∫₀¹ (3^x)² x dx We could write (3^x)² as 3^(2x), or we could notice that this...
