To find out how many cubic inches of water the glass will hold, we need to calculate the volume of the glass. The volume of a cylinder (which is the shape of the glass) is given by the formula V = π * r^2 * h, where V represents the volume, π is a constant approximately equal to 3.14159, r is the radius of the base, and h is the height of the cylinder.
In this case, the radius (r) of the glass is 2 inches and the height (h) is 3 inches. Plugging these values into the formula, we can calculate the volume:
V = π * r^2 * h
= 3.14159 * 2^2 * 3
= 3.14159 * 4 * 3
≈ 37.6991 cubic inches
Therefore, the glass will hold approximately 37.6991 cubic inches of water.
If it is as standard shape of a cylinder, then
volume = π r^2 h
you have both the radius and the height, and your calculator has π as a
built-in function, so go and have fun with it.
