The volume of a right circular cone is 3080 cm3. If the radius of its base is 7 cm, then what is the height of the cone? [Use π = $\frac{22}{7}$]
Answer & explanation
Correct answer: option 1
We know that,
Volume of cone = \(\frac{1}{3}\) πr2h
We have,
The volume of a right circular cone = 3080 cm3
The radius of its base = 7 cm
Now,
\(\frac{1}{3}\) πr2h = 3080
\(\frac{22}{7}\) × (7)2 × h = 3080 × 3
h = 60 cm
