V.t = phi . r" . tV.t = phi . 6 cm . 6 cm . 20 cm
V.t = 720 phi cm^3
V.k = 1/3 . phi . r" . t
V.k = 1/3 . phi . 6 cm . 6 cm . 20 cm
V.k = 240 phi cm^3
V.(k-t) = V.t - V.k
V.(k-t) = 720 - 240
V.(k-t) = 480 phi r"3
Ket :
V.t = Volume tabung
V.k = Volume kerucut
V.(k-t) = Volume tabung di luar kerucut
r" = r kuadrat
