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,
  • \( h \) is the height, and
  • \( \pi \) is a constant approximately equal to 3.14.

Given:

  • The diameter of the cone is 2 cm, which means the radius \( r \) is half of that: \[ r = \frac{2}{2} = 1 \text{ cm} \]
  • The height \( h \) of the cone is 6 cm.

Now substituting the values into the volume formula:

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

Calculating it step-by-step:

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

  2. Substitute \( r^2 \) into the volume formula: \[ V = \frac{1}{3} \times 3.14 \times 1 \times 6 \]

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

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

Therefore, the volume of chocolate needed to make a solid chocolate cone is 6.28 cubic centimeters.

So, the correct answer is:

6.28 cubic centimeters.
