Solid of Revolution Consider the following integral, which calculates the volume of a cylinder by considering it as a solid of revolution: ∫2π0dϕ∫R0drhorhoh, where h is the height, rho is the integration variable of the radius from 0 to R, and ϕ is the integration variable of the angle from 0 to 2π. Solve this integral symbolically. Store your result in a variable volume, which should be a sympy expression. Use the variables names phi for
