According to the question:
Volume of Cylinder (C1) - Volume of Cylinder (C2) = 9240cm3
⇒ 22/7 x 14 x 14 x h - 22/7 x 7 x7 x h = 9240
⇒ 616h - 154h = 9240
⇒ 462h = 9240
⇒ h = 20cm.
New Volume of Cylinder (C2)
⇒ 22/7 x 10.5 x 10.5 x 20 cm3
⇒ 6930 cm3
Volume of Cylinder (C1) = 12320 cm3
Quantity of water remaining in cylinder (C1) = (12320 - 6930)cm3
⇒ 5390 cm3
Hence, the correct answer is 5390cm3.
