Cell phone coverage is in a circular pattern from the tower. If the equation of this pattern is x2 + y2 = 2025, how many miles away from the tower will you have coverage?

OpenStudy (lasttccasey):

Equation of a circle:\[x^2+y^2 = r^2\]Where `r` is the radius of the circle.

OpenStudy (lasttccasey):

So to find r you just take the 2025 and square-root it and you'll have how far it travels from the tower.
