Cups A and B are cone shaped and have heights of 32 cm32cm and 37 cm37cm and openings with radii of 16 cm16cm and 19 cm19cm, 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?

overflow

Explanation:

The volume of a cone is calculated using:

V = 1/3pir^2h" r is radius and h , the height " V=13πr2h r is radius and h , the height

calculate volume of both cones and compare

V_A = 1/3pixx16^2xx32 ≈ 8578.64" cubic cm "VA=13π×162×328578.64 cubic cm

V_B = 1/3pixx19^2xx37 ≈ 13987.42" cubic cm "VB=13π×192×3713987.42 cubic cm

Since V_B > V_A " when poured into A it will overflow "VB>VA when poured into A it will overflow
