there is 4 question on the png form. please answer it in full solution thank you!

Sine vhdady, & the triangle formed by the y-axis, 2y = z, y = 1. Evaluate SJJp f(x, y, 2 ) dadydz where D is the bounded region between the sur faces = =1 -x2 and z = 0 for 0 S y S 2, and f(x, y, z ) = y' Let D be a z-simple cylindrical block Find the volume of the solid bounded be- bounded by the surfaces z = 0 and = = low by the cone z = vx2 + y? and above a + y + 2 and let R denote the projection by the sphere a? + y' + 23 = 1. of D on the ry-plane. Using cylindri cal coordinates, to evaluate the integra JJp(z? + y? )didydz where the project tion R is the region bounded by the cardioid r = 1 + cos 0
