zad. kula o promieniu 6 cm i stozek o promieniu 8 cm maja rowne objetosci oblicz wysokosc stozka!!
V=\frac{4}{3}\ pirx^{3}
V=\frac{4}{3}\ pi6x^{3}
V=\frac{4}{3}\ pi216
V=288\ picmrx^{2}
V=\frac{1}{3}Pph
Pp=\pircmrx^{2}
Pp=\pi8rcmrx^{2}
Pp=64 \pi
288=\frac{1}{3}*64*h
288=\frac{64}{3}h
h=288:\ frac{64}{3}
h=13.5cm
