Respuesta :
General formula for circles at the origin is x^2+y^2=R^2 where R is the radius.So R^2=4225. Solve for R.
Answer:
We can get the coverage up-to 65 miles distance from the tower.
Step-by-step explanation:
Cell phone coverage from a tower can be represented by x² + y² = 4225
This equation is in the form of x² + y² = r², a standard equation for a circle having radius r and center at (0, 0).
When we compare this standard equation with the equation given we find
r² = 4225
r² = (65)²
r = 65
Therefore, we can get the coverage up-to 65 miles.
