extracted_textThe problem asks for the volume of a solid obtained by rotating the region bounded by y=3x2x3y = 3x^2 - x^3 and y=0y = 0 about the y-axis using the shell method. Here's the solution:

(a) Shell Radius, Circumference, and Height

  • Radius: xx
  • Circumference: 2πx2\pi x
  • Height f(x)f(x): The height is given by the function y=3x2x3y = 3x^2 - x^3, so f(x)=3x2x3f(x) = 3x^2 - x^3.

(b) Shell Method Volume Formula

The volume formula using the shell method is: [ V = 2\pi \int_0^a \text{(radius
