To solve this problem you must apply the proccedure shown below:
1. You must apply the formula for calculate the volume of a cone, which is given in the figure attached:
V=πr²h/3
Where r is the radius (r=2 cm) and h is the height (h=3 cm)
2. Therefore, when you substitute these values into the formula for calculate the volume a cone, you obtain the following result:
V=πr²h/3
V=π(2 cm)²(3 cm)/3
V=4π cm³
Therefore, the answer is: The volume of the solide chocolate required is 4π cm³.
