The answer is: glass A - too small, glass B - enough, glass C - too small.
Glasses are cylindrical. The volume of the cylinder is:
V = π r² h (r - radius, h - height)
Glass A:
h = 3 in
d = 2.25 in
r = d/2 = 2.25 / 2 = 1.125 in
____
V = 3.14 * 1.125² * 3 = 11.9 in³ < 50 in³
_____________________
Glass B:
h = 4.25 in
r = 2.4 in
____
V = 3.14 * 2.4² * 4.25 = 76.9 in³ > 50 in³
_______________________
Glass C:
h = 7 in
r = 1.3 in
____
V = 3.14 * 1.3² * 7 = 37.1 in³ < 50 in³
