Please show how you solve these two problems for vector calculus. Please do number 2 PART A AND B, AND number 3 :)

2. Set up, and evaluate integral to find the volume of the solid inside the cylinder x2 + y2 = 4, bounded by z = x + y + 3, and z = 0. Include a sketch of W. A. Using double integral B. Using triple integral 3. Set up and then evaluate integral to find the volume of the solid bounded by z = 138 x2 y2 and the cone 3 = xlxz + y2 . If the density of the solid at any point on the region is proportional to the square of the distance from the origin, set up an integral to nd the mass of the solid
