To calculate 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.
Given:
- The diameter of the cone is 2 cm, which means the radius \( r \) is half of that: \[ r = \frac{2 \text{ cm}}{2} = 1 \text{ cm} \]
- The height \( h \) is 6 cm.
- Use \( \pi \approx 3.14 \).
Now substituting the values into the volume formula:
\[ V = \frac{1}{3} \times 3.14 \times (1 \text{ cm})^2 \times 6 \text{ cm} \] \[ V = \frac{1}{3} \times 3.14 \times 1 \times 6 \] \[ V = \frac{1}{3} \times 18.84 \] \[ V = 6.28 \text{ cubic centimeters} \]
So the volume of chocolate needed to make a solid chocolate cone is \( \boxed{6.28} \) cubic centimeters.
