To find the volume of a cone, you can use the formula:

\[ V = \frac{1}{3} \pi r^2 h \]

where:

  • \( V \) is the volume,
  • \( r \) is the radius of the base,
  • \( h \) is the height of the cone, and
  • \( \pi \) is approximately 3.14.

Given:

  • \( r = 11 \) feet,
  • \( h = 24 \) feet,
  • \( \pi = 3.14 \).

Now, substitute the values into the formula:

\[ V = \frac{1}{3} \times 3.14 \times (11)^2 \times 24 \]

First, calculate \( (11)^2 \):

\[ (11)^2 = 121 \]

Now substitute that back into the volume formula:

\[ V = \frac{1}{3} \times 3.14 \times 121 \times 24 \]

Now calculate \( 121 \times 24 \):

\[ 121 \times 24 = 2904 \]

Now substitute this value back into the formula:

\[ V = \frac{1}{3} \times 3.14 \times 2904 \]

Next, calculate \( 3.14 \times 2904 \):

\[ 3.14 \times 2904 = 9125.76 \]

Now, divide this by 3:

\[ V = \frac{9125.76}{3} \approx 3041.92 \]

Therefore, the volume of the cone is approximately:

\[ \boxed{3041.92} \text{ cubic feet} \]
