How many gallons of water in a 10 foot round pool 2.5 ft deep?

Answer 1

Assuming 10 feet is the diameter: volume of a cylinder is v=pi*r*r*d=pi*5*5*2.5=62.5*pi cubic feet ~ 196.3495 cubic feet

If 10 is the circumference then:

c=pi*d

10=pi*d

10/pi=d

r=5/pi

v=pi*r*r*d

v=pi*(5/pi)*(5/pi)*2.5=pi*[62.5/(pi*pi)]=62.5/pi cubic feet ~ 19.894 cubic feet

Answer 2

4000 gal.
