To find the volume of the cylindrical tanker, we can use the formula:
\[ V = \pi r^2 h \]
where:
- \( V \) is the volume,
- \( r \) is the radius of the cylinder,
- \( h \) is the height (or length) of the cylinder.
Given:
- The radius \( r = 4 \) feet,
- The height \( h = 50 \) feet.
Now we can substitute these values into the formula:
\[ V = \pi (4^2)(50) \] \[ V = \pi (16)(50) \] \[ V = \pi (800) \] \[ V = 800\pi \text{ ft}^3 \]
Thus, the volume of the fuel inside the tank is \( 800\pi \text{ ft}^3 \).
The correct answer is:
800𝜋 ft³
