There are 231 cubic inches in a gallon. A large juice can has a diameter of 6 inches and a height of 10 inches. How many gallons of juice does the can hold? Round your answer to the nearest tenth.
I am clueless please please help me!!!!

Math Nerd,
First find the volume of the large juice can. Since the can is a cylinder, you would use the formula:
V=pir^2h
V=(3.14)(3^2)(10)
V=(3.14)(9)(10)
V=282.6
Divide 231/282.6 to get 0.817 gallons

Divide the volume of the can by the volume of the gallon.
