In this problem, the portion of the cone is given that is z square is equals to x square plus y square and that lies between z is equals to 1 to z is equals to 6.

So we have to find out the value of s into 2z d s.
00:20
Okay so here the surface s can be represented by the surface of the cone can be represented by the equation r t z these are the points so this is z cost t i plus two sign t j plus two here t and z is similar to q okay okay so where q means t is greater than equals to zero and t is less than equals to two pi i and also z is greater than equals to one and small and equals to six so here we have, if we multiply rt and rz, we will get, we have matrix i, z, k minus z sine t, z, c, z, k, z, k, c, coss t, 0, cost, cost t, sine, t, 1.

Here we have compared the equations of surface...
