We know, volume of Cylinder = πr²h
Now, base area = πr² = 3.14 * r² = 7.07
r = √2.25
r = 1.50
Now, volume of water = 3.14 * (1.50)² * 5
v = 3.14 * 2.25 * 5
v = 35.325 in³
Weight of 1 in³ = 0.6 Ounce
so, 35.325 in³ = 0.6 * 35.325 = 21.195 Ounce
Total Weight = Glass weight + water weight
w = 1.06 + 21.195
w = 22.255 Ounce
In short, Your Answer would be 22.255 Ounces
Hope this helps!
