Aat lamina occupies the part of the disk 232 + y2' S 1 in the rst quadrant. The density function is p (3:, y) = my. Find the moment about the y-axis, My. l(If your answer is a fraction, type it in using a forward slash / without any space in between. For example, 1/2. Do not enter a decimal.) A solid is bounded by the upper hemisphere and the xy-plane. The density function is p (:13, y, z) : 3:. Which of the following types of integrals should be used to nd the mass of the solid? 0 tripleintegral O doubleintegral 0 single integral 0 line integral 0 surface integral For the same at lamina and same density function for the previous question, calculuate the x-coordinate of the center of mass for the lamina. Input only the x-coordinate. (If your answer is a fraction, type it in using a forward slash / without any space in between. For example, 1/2. Do not enter a decimal)
