Two circles have the following equations (x -1 )^2+(y -4 )^2= 36 and (x +5 )^2+(y -7 )^2= 49 . Does one circle contain the other? If not, what is the greatest possible distance between a point on one circle and another point on the other?
1 Answer
No, the circle:
Explanation:
In general, out of two circles of radii
the greatest possible distance between two circles with radii
The circle:
hence the distance
hence, the greatest possible distance between given circles is
