kalau d tabungnya 12cm maka r =6cm
r bola = diameter bola/2 = 12/2 = 6cm
v bola = 4/3 (πr³)
= 4/3 (3.14) (6³)
= 904.32 cm³
v tabung = πr²t
= (3.14) (6²) 12
= 1356.48 cm³
v ruang diantara bola dan tabung = v tabung - v bola
= 1356.48 - 904.32
= 452.16 cm³
NB: kalau di soal diketahui r tabung dg nilai yg berbeda. tinggal diganti. dengan cara yg sama. semoga membantu
