question below:

Use cylindrical coordinates to nd the indicated quantity. Volume of the solid bounded above by the sphere x2 +y2 + z2 = 4, below by the plane 2 = 0, and laterally by the cylinder x2 + y2 = 1. E) V = D (Round to four decimal places as needed.) A solid of constant density is bounded below by the plane 2 = 0, above by the cone 2 = r, r 2 0, and on the sides by the cylinder r= 3. Find the center of mass. E) The center of mass is (ii/,9.) = ( I, ,l (Simplify your answer.)
