Find the volume of a right circular cylinder whose height is 15 cm and the radius of the base is 7 cm.
उत्तर
\[ \text{ Given: } \]
\[\text{ Height, h = 15 cm } \]
\[ \text{ Radius, r = 7 cm } \]
\[ \text{ Volume of the right circular cylinder, } V = \pi r^2 h\]
\[ = \frac{22}{7} \times 7^2 \times 15\]
\[ = 2310 {\text{ cm } }^3 \]
