The volume of the ice cream is 72.03 in³.
<h3>What is the volume of the ice-cream?</h3>
The volume of the ice cream is the sum of the volume of the cone and the volume of the hemisphere.
volume of the cone = 1/3πr²h
1/3 x 22/7 x 2.5² x 6 = 39.29
Volume of the hemisphere = 2/3πr³
2/3 x 2.5³ x 22/7 = 32.74
The volume of the ice cream = 39.29 + 32.74 = 72.03 in³
