The volume \( V \) of a cone can be calculated using the formula:
\[ V = \frac{1}{3} \pi r^2 h \]
where:
- \( r \) is the radius of the base of the cone,
- \( h \) is the height of the cone.
Given:
- Radius \( r = 4 \)
- Height \( h = 12 \)
Substituting the values into the formula:
\[ V = \frac{1}{3} \pi (4)^2 (12) \]
Calculating \( (4)^2 \):
\[ (4)^2 = 16 \]
Now substituting back:
\[ V = \frac{1}{3} \pi (16)(12) \]
Calculating \( 16 \times 12 \):
\[ 16 \times 12 = 192 \]
Now substituting this value in:
\[ V = \frac{1}{3} \pi (192) \]
Calculating \( \frac{192}{3} \):
\[ \frac{192}{3} = 64 \]
Thus, the volume \( V \) simplifies to:
\[ V = 64\pi \]
Therefore, the volume of the cone is
\[ \boxed{64\pi} \]
If you want a numerical approximation, you can use \( \pi \approx 3.14 \):
\[ V \approx 64 \times 3.14 \approx 200.96 \]
So the volume is approximately \( 200.96 \) cubic units.
