volume kerucut 3080 cm³ dan diameter alas kerucut 14 cm hitung tinggi kerucut (π=22/7).

Volume = 3.080 cm³
D = 14 cm
r = D/2 = 14/2 = 7 cm

V = 1/3.π.r².t
3.080 = 1/3 x 22/7 x 7 x 7 x t
3.080 = 1/3 x 22 x 7 x t
3.080 x 3 = 154 x t
9.240 = 154 x t
t = 9.240 / 154
t = 60 cm

1/3×22/7×7×7×t = 3080
154/3 t = 3080
t= 3080 × 3/154
t = 60 cm
