![1008 \pi \text{units}^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/k6vtvh4579w2zhj0kzzbkmoqgximuwacii.png)
Explanation:
Volume of cylinder(V) is given by:
![V = \pi r^2h](https://img.qammunity.org/2019/formulas/mathematics/middle-school/xwki3w8vmz5z3pcr7pw21rbxb8o8u1njlt.png)
where,
r is the radius of the cylinder and h is the height of the cylinder respectively.
As per the statement:
Radius of the cylinder(r) = 12 unit and height of the cylinder(h) = 7 units
Substitute the given values in [1] we have;
![V = \pi \cdot 12^2 \cdot 7](https://img.qammunity.org/2019/formulas/mathematics/middle-school/2g740c71zgy50jquen44cscmpc5gmjirp9.png)
⇒
cubic units.
Therefore, the volume of the cylinder is,
![1008 \pi \text{units}^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/k6vtvh4579w2zhj0kzzbkmoqgximuwacii.png)
