General formula for all pointed spatial figures (e.g. pyramid, cone) is given as: V = 1/3bh where b is the area of the base and h is the altitude or the height perpendicular with the horizontal. ----------------- Since the base of a cone is circle then 'b' can be expressed as: b = πr² or you'll have the formula for the volume of the cone as: V = 1/3 π r² h
