Deduction of the volume of a wedge

It is very easy!! We apply the process by which there is calculated the value of a directly proportional magnitude to other one, ie, we use a rule of three direct.

We know that the volume of a sphere is: {4/3Pi.R^3}. So, we have the following:

{4/3Pi.R^3} right360º
                                         ⇒    x=   {{4/3Pi.R^3.nº}/{360º}}= tabular{11}{11}{{{Pi.r^3.nº}/{270º}}};-)
x          right

being n º the number of degrees that the wedge includes and x the volume that we want to calculate (the mystery).
