Use a parametrization to express the area of the surface as a double integral. Then evaluate the integral. The lower portion cut from the sphere x squared plus y squared plus z squared equals 25x2+y2+z2=25 by the cone z equals StartFraction 3 Over StartRoot 3 EndRoot EndFraction StartRoot x squared plus y squared EndRootz= 3 3x2+y2

according to egenuity the answer is
