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, and \( h \) is the height.

  1. First, calculate the radius from the diameter:

    • Diameter = 12 cm, so Radius \( r = \frac{12}{2} = 6 \) cm.
  2. Next, substitute the radius and height into the formula:

    • Height \( h = 11 \) cm.
    • Volume \( V = \frac{1}{3} \pi (6^2)(11) \).
  3. Calculate \( 6^2 \): \[ 6^2 = 36 \]

  4. Now plug the values into the volume formula: \[ V = \frac{1}{3} \pi (36)(11) \] \[ V = \frac{1}{3} \pi (396) \] \[ V = 132 \pi \]

  5. Using \( \pi \approx 3.14 \): \[ V \approx 132 \times 3.14 \approx 414.48 , \text{cubic centimeters} \]

So, the volume of the cone is approximately 414.48 cubic centimeters.
