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

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

where:

  • \( V \) is the volume,
  • \( r \) is the radius,
  • \( h \) is the height,
  • \( \pi \) is a constant (approximately 3.14 in this case).

Given:

  • Diameter = 2 cm, which means radius \( r = \frac{2}{2} = 1 \) cm
  • Height \( h = 6 \) cm

Now substituting the values into the formula:

\[ V = \frac{1}{3} \times 3.14 \times (1)^2 \times 6 \]

Calculating this step by step:

  1. Calculate \( r^2 \): \[ (1)^2 = 1 \]

  2. Plug in the values: \[ V = \frac{1}{3} \times 3.14 \times 1 \times 6 \]

  3. Calculate \( 3.14 \times 1 \times 6 \): \[ 3.14 \times 6 = 18.84 \]

  4. Now, calculate \( \frac{1}{3} \times 18.84 \): \[ \frac{18.84}{3} = 6.28 \]

Thus, the volume of the chocolate cone is \( 6.28 \) cubic centimeters.

The correct response is: \[ \text{6.28 cubic centimeters} \]
