Cups A and B are cone shaped and have heights of 20 cm and 12 cm and openings with radii of 5 cm and 8 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?

Since volume of cup B (2412.7432) > volume of cup A (523.5988), #excess quantity of 1889.1444 cc from Cone B will overflow.

Volume of a cone V = (1/3) pi r^2 h

Given : r_a = 5 cm, r_b = 8 cm, h_a = 20 cm, h_b = 12 cm

V_a = (1/3) * pi * 5^2 * 20 = 523.5988 cc

V_b = (1/3) * pi * 8^2 * 12 = 2412.7432 cc

Since volume of cup B (2412.7432) > volume of cup A (523.5988), #excess quantity of 1889.1444 cc from Cone B will overflow.
