Circular pool volume..

[anemone]

Hello!
Im a bit confused by the formulas on the web on how to calculate the volume
of a round kids pool....here are some of the formulas with the answers that
i have

Diameter x Diameter x Average Depth x 780 = Total Litres (216L)

(? x Radius2 x Depth) x 1000 litres= total litres (572L)

A you can see I got 2 completely different numbers!!!

The pool is 1.52m in radius and .12m (12cm) in depth...

Can anyone help me here???
Cheers

I would use the area of a circle times the depth of the pool to get the
volume in meters. Then convert the meters to gallons or litres (which ever
you prefer)

Area of a circle = pi * Radius ^2

Based on the radius you provided I calculate a volume of roughly 871,000
cubic centimeters.
152cm^2*pi*12cm=871000.28
If memory serves me right, 1 ml of water occupies 1cm^3 of space.
Therefore, you have 871,000 ml of water which seems to be about 871 litres.
This is obviously based on a straight up and down wall, flat bottom and
perfectly round pool, but it will give you a really good idea of how much
water you're dealing with.

871 litres...
it seems a bit much for this little pool...(it fits in my small room!)...
hang on....****...sorry....i meant to say diameter for
1.52cm.....geez..wheres my brain today.!!!!
Sorry!

Remember when we used to complain about our math saying, "When am I ever
going to need to use that?".
Well, now you have a perfect example.

I keep a little booklet on my shelf which contains all those formulas
that come handy only every 10 years or so. Thus I only need a dim
recollection of maths to find the right formula, and for that the school
stuff is indeed handy!

I commend you merely for being able to find the book.

That commendation should go to my maths teacher then, this one is the
only of my school books that I still use, 25 years after graduating!
