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!!!!

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 
Find the volume of the can (cylinder).

Divide the volume of the can by the volume of the gallon. 
so the answer is 0.817 gallons when you round to the nearest tenth?

THANK YOU so so so much!!

The answer is 0.8 gallons when rounded to the nearest 10th.

0.817 is not rounded to the nearest tenth.
0.8 
find the number of quarts in 73,458 cubic inches of water. There are 231 cubic inches in 1 gallon.

Answer is 1.2 gallons
