Diameter alas sebuah tabung20 dm, jika volume tabung 4.710 dm^3, berapa dm tingginya kakak abang tolong di jawab

D = 20 dm → r = 10 dm maka, V tabung = 4.710 phi x r² x t = 4.710 3,14 x 10² x t = 4.710 3,14 x 100 x t = 4.710 314 x t = 4.710 t = 4.710 : 314 t = 15 dm
maka,
V tabung = 4.710
phi x r² x t = 4.710
3,14 x 10² x t = 4.710
3,14 x 100 x t = 4.710
314 x t = 4.710
t = 4.710 : 314
t = 15 dm
