The volume of a right circular cone is 616 cm3. If the area of its base is 154 cm2, what is the vertical height of the cone? [Use π = $\frac{22}{7}$]
Answer & explanation
Correct answer: option 2
We know that,
Volume of a right circular cone = \(\frac{1}{3}\) πr2h
616 = \(\frac{1}{3}\) (154) × h
\(\frac{616 × 3}{154}\) = h
h = 12
