Solution
Given:
Diameter, d = 42 cm
\[\text{ Radius, r }= \frac{d}{2} = 21 cm\]
Height, h = 10 cm
\[\text{ Volume of the cylinder, }V = \pi r^2 h\]
\[ = \frac{22}{7} \times {21}^2 \times 10\]
\[ = 13860 {cm}^3\]
Diameter, d = 42 cm
\[\text{ Radius, r }= \frac{d}{2} = 21 cm\]
Height, h = 10 cm
\[\text{ Volume of the cylinder, }V = \pi r^2 h\]
\[ = \frac{22}{7} \times {21}^2 \times 10\]
\[ = 13860 {cm}^3\]
