OK, Jan. The circumference is the distance around the circle. Say you
have a round pond that's ten foot across. You'll need 31.4 feet of
edging stones. Say it's ten feet deep and you want to tile the side.
You'll need 314 sq. ft. of tile.

It would hold 3.14*5*5*10*7.48= 5872 gallons.

Pi (3.14) X radius squared X diameter X 7.48 = gallons

How's that? ~ jan

Pi (3.14) X radius squared X DEPTH X 7.48 = gallons
