It seems like you are trying to calculate the volume of a cylinder, but the formula you've provided is actually for the volume of a sphere.
For the volume of a cylinder, the formula is: \[ V = \pi r^2 h \] where:
- \( r \) is the radius,
- \( h \) is the height, and
- \( \pi \) is approximately 3.14.
Given:
- \( r = 2 \) feet,
- \( h = 4 \) feet.
Now, you can substitute the values into the formula:
\[ V = \pi (2)^2 (4) \] \[ V = 3.14 \cdot 4 \cdot 4 \] \[ V = 3.14 \cdot 16 \] \[ V \approx 50.24 \text{ cubic feet} \]
So, the volume of the cylinder is approximately 50.24 cubic feet.
