प्रश्न
Find the volume of a cone if the radius of its base is 1.5 cm and its perpendicular height is 5 cm.
उत्तर
Radius of the cone, r = 1.5 cm
Height of the cone, h = 5 cm
∴ Volume of the cone, V = \[\frac{1}{3}\pi r^2 h = \frac{1}{3} \times \frac{22}{7} \times \left( 1 . 5 \right)^2 \times 5 =\] 11.79 cm3
Thus, the volume of the cone is 11.79 cm3.
