To find the volume of a cone, you need to use the formula V = (1/3)πr^2h, where r is the radius of the base and h is the height.
Given that the diameter of the cone is 2 cm, the radius would be half of that, which is 1 cm.
Plugging in the values, the volume of the chocolate cone would be V = (1/3)(3.14)(1^2)(6).
Simplifying, V = (1/3)(3.14)(1)(6) = 6.28 cubic centimeters.
Therefore, the correct answer is 6.28 cubic centimeters.

To find the volume of the sandcastle mold, we can use the formula V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.

Given that the diameter of the mold is 4 meters, the radius would be half of that, which is 2 meters.

Plugging in the values, the volume of the sandcastle mold would be V = (1/3)(3.14)(2^2)(6).

Simplifying, V = (1/3)(3.14)(4)(6) = 25.12 cubic meters.

Therefore, the correct answer is 25.12 cubic meters.
