radius=6 feet

height=12 feet
V=4/3 3.14r3

1 answer

It looks like you're trying to calculate the volume of a shape using the formula \( V = \frac{4}{3} \pi r^3 \), which is the formula for the volume of a sphere, not a cylinder. However, you've provided a radius and height, which may indicate you are looking for the volume of a cylinder.

Volume of a Cylinder

The volume \( V \) of a cylinder can be calculated using the formula:

\[ V = \pi r^2 h \]

where:

  • \( r \) is the radius,
  • \( h \) is the height.

Given:

  • \( r = 6 \) feet
  • \( h = 12 \) feet

Calculation:

  1. Calculate \( r^2 \): \[ r^2 = 6^2 = 36 \text{ square feet} \]

  2. Plug in the values: \[ V = \pi \times 36 \times 12 \]

  3. Calculate \( \pi \times 36 \times 12 \): \[ V = 3.14 \times 36 \times 12 = 3.14 \times 432 \] \[ V = 1357.68 \text{ cubic feet} \]

Conclusion

The volume of the cylinder is approximately 1357.68 cubic feet.

If you intended to find the volume of a sphere instead, let me know!
