What is the height of a cylinder whose radius of base is 12 cm and volume is 19008 cm3 ? [Use π = $\frac{22}{7}$]
Answer & explanation
Correct answer: option 4
We know that,
Volume of a cylinder = πr2h
Radius = 12 cm
Volume = 19008 cm3
\(\frac{22}{7}\) × 122 × h = 19008
= \(\frac{22}{7}\) × 144 × h = 19008
= h = 19008 × \(\frac{7}{3168}\)
= h = 42
