For a cone, $r = 1.4 c m$ and $h = 6 c m$ . Find the volume of the cone. ( $π = 22 / 7$ )

Open in App

Solution

Radius of cone is $1.4 c m$

Height of cone is $6 c m$

Let the volume of cone be $V$

$V = \frac{1}{3} π r^{2} h = \frac{1}{3} \times \frac{22}{7} \times 1.4 \times 1.4 \times 6 = 22 \times .2 \times 1.4 \times 2 = 12.32 c m^{2}$
