A 15 cm Correct Answer Incorrect Answer
B 5 cm Correct Answer Incorrect Answer
C 10 cm Correct Answer Incorrect Answer
D 12.5 cm Correct Answer Incorrect Answer
E 7.5 cm Correct Answer Incorrect Answer

Solution

Volume of cylinder = πr2h where r = radius and h = height ⇒ 24640 = 22/7 x 28 x 28 x h ⇒ h = 10 cm So, height of cylinder = 10 cm
