What is the height of a cylinder whose radius of the base is 12 cm and volume is 19008 cm3? [Use π = 22/7 ]
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 42 cm.
Radius = 12 cm
Volume = 19008 cm3
Volume of cylinder = πr2h ----- (1)
Where, r = radius and h = height
Using equation (1), we get
⇒ (22/7) × 12 × 12 × h = 19008
⇒ h = 6 × 7
⇒ h = 42 cm
