Question 472456
Please help me solve this problem: Two circles have their centers at (2, 4) and (-14, 2) and they intersect at the point (-2, 7). What is the radius of each circle?
-------------
The radius is the distance from the center to the point (-2,7).
From (2,4) to (-2,7):
{{{d = sqrt(diffy^2 + diffx^2) = sqrt(4^2 + 3^2)}}}
r = 5
------------
For the other one:
{{{d = sqrt(diffy^2 + diffx^2) = sqrt(12^2 + 5^2)}}}
r = 13
