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 = $\frac{22}{7}$] |
60 cm 80 cm 120 cm 90 cm |
60 cm |
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 |
