)lane. The radius r is afunction of z whicli is given by the equation of the generatrix r = F(z). Hence the equationof the surface of revolution is obtained by eliminating /• fromthe equations af + y- — r and r = F(z). … Problems. — 1. Find equation of surface of sphere, center at origin,radius li. This sphere is generated by the revolution about the Z-axis ofa circle whoso e(iualion is r~ + z- = R-. Eliminate r from this equationand x- -|- y- — ?•-, and the ecpiation of the sphere is found to be X- -f if -V Z^:=…
