A professional baker uses a chocolate mold to make decorations for cakes. One chocolate mold is in the shape of a cone and has a diameter of 2 cm and a height of 6 cm. What volume of chocolate, in cubic centimeters, is needed to make a solid chocotate cone? Use 3.14 for π. (1 point)

6.28 cubic centimeters

37.68 cubic centimeters

12.56 cubic centimeters

18.84 cubic centimeters

To find the volume of the cone, you can use the formula for the volume \( V \) of a cone:

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

where \( r \) is the radius and \( h \) is the height of the cone.

  1. Find the radius: The diameter of the cone is 2 cm, so the radius \( r \) is: \[ r = \frac{2 \text{ cm}}{2} = 1 \text{ cm} \]

  2. Height: The height \( h \) is given as 6 cm.

  3. Substitute the values into the 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 6.28 cubic centimeters. Thus, the correct answer is:

6.28 cubic centimeters.
