A water bottle has a height of 16 inches and a radius of 4 inches. What is the volume, in cubic inches, of the water bottle?
The volume of a cylinder can be calculated using the formula V = πr^2h, where r is the radius and h is the height. Given that the radius is 4 inches and the height is 16 inches, we can substitute these values into the formula:
V = π(4^2)(16)
= π(16)(16)
= 256π
So, the volume of the water bottle is 256π cubic inches.
