Secondary level question
What is the formula to figure the volume of a cylinder? We have a cylinder that is 2 3/4" in inside diameter and a gallon of oil that needs to fill it. We are trying to figure out how long the cylinder should be. Can you help us?
Are you sure you want a gallon? A gallon is 231 cubic inches. The volume of a cylinder is pi*r2*h and if d = 2.75, then to get the height of the cylinder you divide 231 by pi*r2 which is about 231 over 3.14159*(2.75/2)2. I get height = 38.8917 (which is more than 3 feet high!).Cheers,
