Did you mean spherical water tank?

or

water tank is a cylinder with a circular base?

"about 6 feet from the circular tank" ---- 6 feet to the closest point of the tank?

or

" the distance from you to a point of tangency on the tank is about 10 feet"

- if it is a sherical water tank, then there are two tangents, one horizontal and one which is slanted.

????
