Oblicz gęstość kuli: V = 4/3*[latex]v = frac{4}{3}*3,14*r^{3}[/latex] r=3cm

[latex] r = 3cm \ V = frac{4}{3} imes 3,14 imes r^3 \ \ \ V = frac{4}{3} imes 3,14 imes (3cm)^3 = 63,585 cm^3 [/latex]       ---------------------------------------------------------------------------------------------------- Litterarum radices amarae sunt, fructus iucundiores   Pozdrawiam :)
