you have a full cylindrical glass of water that stands 8 inches tall and has a radius of 1.5 inches. If you pour the water into a larger cylindrical glass that stands 12 inches tall and has a radius of 2.5 inches, how much more water would the larger glass be able to hold? round your answer to the nearest hundreth.



Answer :

AL2006
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)
