The volume of a cylinder is [ (pi) (radius)² (height) ] .
The volume of the big glass is [ (pi) (2.5)² (12) ] = 75 pi cubic inches.
The volume of the small glass is [ (pi) (1.5)² (8) ] = 18 pi cubic inches.
When you empty the small glass into the large one, the large one still has
room for [ (75 pi cubic inches) minus (18 pi cubic inches) ] more water.
(75 - 18) (pi) cubic inches = 57 pi cubic inches = 179.07 cubic inches
(about 99.22 fluid ounces)
