How many gallons of a chemical can be stored in a cylindrical tank if the radius of the tank is 15 feet? One gallon is equal to 231 cubic inches.

(1) The height of the tank is 20 feet.
(2) The temperature is 60 degrees Fahrenheit

S1 - height=20ft
Volume of cylindrical tank=$$πr^2h$$
The units can be converted to cu.in from cu.ft. and then to gallon as per conversion rate given.
Sufficient.

S2-Insufficient.

St 1 :, as we got both radius and height. Volume of chemical stored can be found. Sufficient
St2: temperature is irrelevant. So insufficient.

PS:since the question ask for volume temperature of stored chemical is not relevant. If the question had been of mass of chemical stored, then temperature and the density of chemical at the stored temperature would be required to find mass of chemical stored.

Give Kudos, if you like my explanation.
