Question 632170
V = pi*r^2*h



V = pi*(18)^2*(72)



V = 23328pi  <font color="blue"><<< --- Exact Volume</font>



V = 23328(3.14159)



V = 73287.01152 <font color="red"><<< --- Approximate Volume</font>



So the approximate volume is 73287.01152 cubic inches.



Now convert this to gallons



(73287.01152 cubic inches)*(1 gallon/231 cubic inches) = 73287.01152/231 = 317.25979012987



and round it to get 317.2598



So the tank can hold approximately <font color="red">317.2598 gallons</font>.
