Q1. Find the centroid of the solid bounded by the surfaces 2: = 1 322, z = U, y = 1 and y = 1 assuming the solid has a uniform mass density.r 5(22, y, z) = 1. Average Value: The average value of a multivariable function rs, y) on a region R can be calculated using the scaled double integral: Are:[R) ]f[m,y)dA (1) s
