Find the volume of a cylinder, if the diameter (d) of its base and its altitude (h) are: d = 7 m, h = 24 m .
उत्तर
\[ \text{ Given } : \]
\[d = 7 \text{ m, radius, } r = \frac{d}{2} = 3 . 5 m\]
\[ \text{ height h = 24 m } \]
\[\text{ Volume of the cylinder, V } = \pi r^2 h\]
\[ = \frac{22}{7} \times \left( 3 . 5 \right)^2 \times 24\]
\[ = 924 m^3\]
