Q. Use the shell method to find the volume of the solid generated by revolving the shaded region about the x-axis.Set up the integral that gives the volume of the solid.The volume of the solid generated by revolving the shaded region about the x-axis is □ cubic units. (Type an exact answer, using π as needed.)
Identify function & limits: Identify the function and limits for the shaded region. Assume the function is y=x2 from x=0 to x=2.
Set up integral: Set up the integral using the shell method. The radius of each cylindrical shell is x, and the height is the function value y=x2. The volume of each shell is approximately 2πxydx.
Write integral for volume: Write the integral for the volume: V=∫022πx(x2)dx. Simplify the integrand to 2πx3.
Calculate integral: Calculate the integral: V=2π∫02x3dx.
Solve integral: Solve the integral: ∫x3dx=4x4. Evaluate from 0 to 2, which gives (424)−(404)=416−0=4.
Multiply by 2π: Multiply by 2π: V=2π×4=8π cubic units.
