Volume of a circular pool is given by pi*r^2*h(in this case h is the depth)---a cylinder. Since you don't specify the depth, the radius can be anything that you want it to be----depending on what value you choose for the depth.

depends on the depth of the pool.

If the pool is circular, the formula for volume is

you get

v = 1000 so you get

you can solve for r or you can solve for h.

if you solve for r, you get =

take square root of both sides of equation and you get:

r = +/-

if you solve for h, you get

assuming the depth of the pool is 6 feet all around, the radius would be:

r = +/- feet.

graph of equation for the radius is shown below:

y value represents the radius of the pool.
x value represents the depth of the pool.

you can see that when the depth of the pool is 1 foot, the radius of the pool is:
