Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.
First, you multiply 2.2 by itself to get the diameter, and then multiply the answer you got by the height: 2.2 times 2.2 equals 4.84, then 4.84 times 4.9 equals 23.716. 23.716 is the answer. 23.716 yd3
