================================================== ===
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ
d = 140 cm, r = 70 cm
t = 150 cm
Volume of total water
= Πr²t
= 22/7 × 70 × 70 × 150
= 22/1 × 10 × 70 × 150
= 220 × 10,500
= 2,310,000 cm³
Volume of water if filled with 2/3 parts
= 2/3 parts × Total volume
= 2/3 × 2,310,000
= 2x770,000
= 1,540,000 cm³ or
= 1,540 Liters

volume = Π × r × r × T
= 22/7 × 70 × 70 × 150
= 2310000 × 2/3 = 15,40000
the volume of water in the tub is
2310000-1540000 = 770000
