Help me with all qustion please.

Let C be a solid cone with both height and radius of l and contained between the surfaces 2' = 1M2 + y2 andz = 1. KC has the density 8(x,y,z) : 22 gln-fC-l'l'l3, nd a. The mass ofC. b. [The zcoordinate of C's center of mass. [8pts] If we have a function, _f(x, y, z) , which gives the charge density (charge per unit area) over a surface S, then the surface integral would give us the total charge on the surface of S. Calculate the total charge on a cone whose base is the disk x2 + y2 = 4 in the Ajv plane with a height of 4cm and a charge density of f(x, y, z) = A" + y + z C,-""cmz
