Question 1062760: A cylindrical pail has a radius of 7 inches and a height of 9 inches.If there are 231 cubic inches to a gallon, approximately how many gallons will this pail hold?

the volume is equal to pi * r^2 * h.
since r = 7 and h = 9, then the volume is equal to pi * 7^2 * 9 which makes the volume equal to 1385.44236 cubic inches.
since a gallon is equal to 231 cubic inches, then the volume of the pail is equal to 1385.44236 / 231 = 5.997585975 gallons.
round this to the nearest gallon and you have approximately 6 gallons.
