V kerucut = 1/3 x \pi x r² x t
120 = \pi r² t


v baru = 1/3 x \pi x (2r)² x (3t)
v baru = \pi x 4r² x t
v baru = 4 ( \pi x r² x t)
v baru = 120 x 4
v baru = 480 cm³


Maaf jika salah

V kerucut = 1/3 x phi x r^2 x t
120 = phi r^2 t


v baru = 1/3 x phi x (2r)^2 x (3t)
v baru = phi x 4r^2 x t
v baru = 4 ( phi x r^2 x t)
v baru = 4 x 120
v baru = 480 cm^3
