The radius is the distance between the centre and the given point, which is
r=sqrt(15^2+4^2)=sqrt(241)
The circle with centre (2,-5) is
(x-2)^2+(y-(-5))^2=r^2
There is only one choice that fits these criteria.
53. What is the equation of the circle with center (2, –5) that passes through the point (–2, 10)? (1 point)
(x – 2)2 + (y – (–5))2 = 25
(x – (–2))2 + (y – 10)2 = 241
(x – 2)2 + (y – (–5))2 = 241
(x – (–2))2 + (y – 10)2 = 25
