To do this correctly, you need the *inside* dimensions. Assuming that's what you have,
D = 3"
r = ½D = 1½"
h = 4⅝"
Then use these definitions & formulas:
Area of a circle, A = π r²
Volume of a cylinder, V = Ah = π r² h
1 gal (US) = 231 in³
1 fl oz = 1/128 gal (US) = 231/128 in³ = 1.8046875 in³
V = (37/8) in • (9/4) in²
= (333/32)π in³ • 1
= (1332/128)π in³ • (fl oz / [231/128 in³])
= (1332/231) fl oz = (444/77) fl oz
= 5.766 fl oz
which is just about 5¾ ounces.
