If we cut a sphere with a plane or some planes, we obtain different spherical figures and also we obtain different regions on the spherical surface:

         Area(spindle)= tabular{11}{11}{{{4.Pi.r^2.nº}/{360º}}}         How can you deduce this formule?

         Volume(wedge)= tabular{11}{11}{{{Pi.r^3.nº}/{270º}}}         How can you deduce this formule?

         Area(skull-cap)= tabular{11}{11}{{2.Pi.r.h}}         How can you deduce this formule?

         Volume(segment)=tabular{11}{11}{{h.Pi(3r^2 + h^2)/6}}
