Volume Tabung
= πr²t
= 22/7 × 14² × 30
= 22/7 × 196 × 30
= 22 × 28 × 30
= 616 × 30
= 18.480 Cm³.
Volume 3 Bola
= 3 × 4/3πr³
= 3 × 4/3 × 22/7 × 7³
= 1 × 4 × 22/7 × 343
= 4 × 22 × 49
= 88 × 49
= 4.312 Cm³.
Volume Akhir
= 18.480 + 4.312
= 22.792 Cm³.
Penyelesaian
Volume Akhir = πr²t
22.792 = 22/7 × 14² × t
22.792 = 22/7 × 196 × t
22.792 = 22 × 28 × t
22.792 = 616 × t
Tinggi = 22.792/616
Tinggi = 37 Cm

Penjelasan dengan langkah-langkah:
v. tabung = πr² x T
= 22/7 x 14 x 14 x 30
= 22 x 2 x 14 x 30
= 18.480
V 3 bola = 3 x 4/3 πr³
= 3 x 4/3 x 22/7 x 7 x 7 x 7
= 4 x 22 x 1 x 7 x 7
= 88 x 49
= 4. 312
v. Tabung + V. bola = 18.480 + 4. 312
= 22. 792
ditanyakan Tinggi air saat ini ?
V = π r² x Tinggi tabung sekarang
22.792 = 22/7 x 14 x 14 x T
22. 792 = 22 x 2 x 14 x T
22. 792 = 22 x 28 x T
22. 792 = 616 T
T = 22.792 / 616
T = 37 Cm
