Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on
convert-me.com FaceBook pageThank you for being with us and sorry for any inconveniences this could caused.

I have a cylindrical water well that is three feet in diameter and fifteen feet deep. I need
to know how many gallons it contains in or to chlorinate it at the rate of a quart per thousand gallons.
All I really need is to know how many gallons it contains when full.

Aliquid gallon is 231 cubic inches. So first you have to convert your height to inches
The formula is:
15x20=300 inches
since diameter = 36 inches:
radius = 1/2 (diameter) = 18 inches
.
area of bottom of well = (pi)r^2 = (pi)18^2 = 1017.87 square inches
volume = "area of bottom" * height = 1017.87 * 300 = 300,361 cubic inches
.
# of gals in well = "volume of well"/"volume of 1 gal of water"
# of gals in well = 300361/231 = 1,300.26 gallons
So 1.3 quarts
