Estimate 4-5ft of 3/8" tubing, how much freon?

About how much freon does a 4-5ft of 3/8" tubing take? This is for the high side, r134a.

Thanks.

Volume = pi r2 L = cubic inches

pi=3.14
r2=1/2 of ID squared (inches)
L= length (inches)

You will then need P/T to determine density of 134a at that point and apply.
