... If we take projections on the XY plane, the area is bounded by the circle $x^2 + y^2 = 2$, the line y = x and the line x = 0. We change the coordinate to cylindrical polar by putting x = $rcos \theta, y = rsin \theta$, z = z . Eqn. of the cylinder becomes $x^2 + y^2 = 2 \Rightarrow r = \sqrt{2}$ t ...

Let the equation of the sphere be$x^2 + y^2 + z^2 =a^2$. Using cylindrical polar coordinate$x = rcos \theta, y = rsin \theta, z = z$we see that in the first octant z varies from z = 0 to$z = \sqrt{a^2 - (x^2+y^2)} = \sqrt{a^2 - r^2}$r varies from r = b to r = a and$\theta$varies from$\thet ...
