To find the volume of a cone, we use the formula:

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

where \( V \) is the volume, \( r \) is the radius of the base, and \( h \) is the height of the cone.

Given:

  • Radius \( r = 11 \) inches
  • Height \( h = 24 \) inches

We can plug these values into the formula:

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

Calculating \( (11)^2 \):

\[ 11^2 = 121 \]

Now substituting back into the volume formula:

\[ V = \frac{1}{3} \pi (121)(24) \]

Calculating \( 121 \times 24 \):

\[ 121 \times 24 = 2904 \]

Now substituting this back into the equation for volume:

\[ V = \frac{1}{3} \pi (2904) \]

Calculating \( \frac{2904}{3} \):

\[ \frac{2904}{3} = 968 \]

Now we substitute this into the formula for volume:

\[ V = 968 \pi \]

Using the approximation \( \pi \approx 3.14159 \):

\[ V \approx 968 \times 3.14159 \approx 3042.11072 \]

Rounding to the nearest hundredth, we get:

\[ V \approx 3042.11 \]

Thus, the volume of the cone is

\[ \boxed{3042.11} \text{ cubic inches.} \]
