If 3cm is the radius and 14cm is the height, the volume would be 131.95cm^3. In terms of pi it would be 9pi(14/3).
In the morning
(3/4) (strawberries / minutes) * (60/1) (minutes / hours) = 45 (strawberries / hours)
in the afternoon
(2/3) (strawberries / minutes) * (60/1) (minutes / hours) = (40 strawberries / hours)
the difference between your morning and afternoon packing rates, in pints per hour is
45-40 = 5 (strawberries / hours)
