Answer:
18.75π cubic inches
Explanation:
Diameter of the cone = 3 inch
Since radius is half of the diameter, the radius of the cone will be = r = 1.5 inch
Height of the cone = h = 25 inch
The formula to calculate the volume of the cone is:

Using the given values in this formula, we get:

Thus, the exact volume of the cone will be 18.75π cubic inches
