This glass is 15cm tall, the diameter of the bottom is 6cm and the diameter at the top is 9cm.
How much water can it hold?
You can draw this diagram:
The glass is represented by the shaded area (15,6,9cm). Extend the truncated cone; the volume of the
glass is the volume of the whole cone (45cm tall) minus the volume of the cone below the glass (30cm tall).
pi x (9/2)^2 x 1/3 45 = ~954 cc
pi x (6/2)^2 x 1/3 30 = ~283 cc
glass volume is 954-283 = 671 cc ~= 24 floz
One fluid ounce is about 28cc. Convert the volume to floz.
