Question

What is the standard form of the equation of a circle with its center at (2, -3) and passing through the point (-2, 0)?

A-(x − 2)2 + (y + 3)2 = 5

B-(x + 2)2 + (y − 3)2 = 25

C-(x − 2)2 + (y + 3)2 = 25

D-(x − 2)2 − (y + 3)2 = 5

Answer 1

equation of circle is \[\huge\rm (x-h)^2 + (y -k)^2 = r^2\]where (h,k) is the center
r = radius
and (-2,0) = (x,y)

Answer 2

replace variables by their values solve for r
