The diameter of an ice-cream cone is $7 c m$ and its height is $12 c m$ . Find the volume of ice-cream that the cone can contain.

Open in App

Solution

Radius, $r = \frac{7}{2}$ cm
Height, $h = 12$ cm
Therefore,
Volume $= \frac{1}{3} π r^{2} h$

$= \frac{1}{3} \times \frac{22}{7} \times (\frac{7}{2})^{2} \times 12$

$= 154$ $c m^{3}$
