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

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

Where:

  • \( V \) is the volume,
  • \( r \) is the radius,
  • \( h \) is the height of the cone.

Given:

  • The diameter of the cone is 2 cm, so the radius \( r \) is \( \frac{2}{2} = 1 \) cm.
  • The height \( h \) is 6 cm.
  • Use \( \pi \approx 3.14 \).

Now, plug in the values:

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

Calculating step-by-step:

  1. Calculate the radius squared: \[ 1^2 = 1 \]

  2. Now calculate the volume: \[ V = \frac{1}{3} \times 3.14 \times 1 \times 6 \] \[ V = \frac{1}{3} \times 3.14 \times 6 \] \[ V = \frac{1}{3} \times 18.84 \] \[ V = 6.28 \]

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

So the correct response is:

6.28 cubic centimeters.
