Cups A and B are cone shaped and have heights of 37 cm and 27 cm and openings with radii of 9 cm and 4 cm, respectively. If cup B is full and its contents are poured into cup A, will cup A overflow? If not how high will cup A be filled?

Will not overflow and it has a height of 5 1/3cm

Explanation:

Volume of the cone is given by 1/3pitimesr^2timesh
where h is the height and r is the radius

Volume of Cup B: 1/3pir^2h = 1/3pitimes4^2times27 = 144pi

Volume of Cup A: 1/3pir^2h = 1/3pitimes9^2times37 = 999pi

Therefore, Cup A will not overflow

Now, we need to find the height of Cup A

1/3pir^2h = 144pi

1/3pitimes9^2timesh=144pi

27pih=144pi

h=5 1/3cm
