V 1/2 bola = V 1/3 kerucut 1/2 x 4/3 x π x r^3 = 1/3 x 1/3 x π x r^2 x t 2/3 x 6 x 6 x6 = 1/9 x 9 x 9 x t ( phi-nya dicoret) 144 = 9 t 16 = t Jadi, t kerucut = 16
4/3 πr3 = 1/3 x 1/3 x π x r2 x t
4/3 x 3.14 x 216 = 1/3 x 1/3 x 3.14 x 81 x t
452.16 = 28.26 t
t = 452.16/28.26
t = 16 cm = a
1/2 x 4/3 x π x r^3 = 1/3 x 1/3 x π x r^2 x t
2/3 x 6 x 6 x6 = 1/9 x 9 x 9 x t ( phi-nya dicoret)
144 = 9 t
16 = t
Jadi, t kerucut = 16
