- The following problem is similar in spirit to some which were studiedby Archimedes and others. Solve it using integral calculus: Let Ah be the closed regionin the coordinate plane defined by the vertical lines 1 = x and x = h (where h > 1), thex-axis, and the hyperbola y =((x^2) − 1)^1/2, and let Bh be the corresponding region definedby the vertical lines 0 = x and x = h (where h > 0), the x-axis, and the hyperbola’sasymptote y = x. Next, let Ph and Qh be the solids of revolution obtained by rotating Ahand Bh (respectively) about the x-axis. Compute the ratio|Vol (Ph)|/|Vol (Qh)|.[Hint: Draw a picture to make the problem more transparent.]How do I set up the triple integral of the function xy2 -3z, where the solid is bounded by the sphere x2 + y2 + z2 = 25, the cylinder x2 + y2 = 9, and the xy-plane, using spherical coordinates? Solving these integrals by hand is way too difficult, so I just need to find the limits of integration in terms of ρ, φ, and θ.what is the area of the rotational surface formed by rotating the part of the function y= x^3/3 between 0<x<1 around the Ox axis
