standard form of the equation of the circle with the radius r and center (h,k). r=10: (h,k)=(4,-10)

Question

possible answers:

(x+4)2+(y-10)2=100

(x+4)2+(y-10)2=10

(x-4)2+(y+10)2=100

(x-4)2+(y+10)2=10

Answer 1

Standard form of a circle centered on (a,b) with radius = r:

(x - a)^2 + (y - b)^2 = r^2

Standard form of a circle centered on (4,-10) with radius = 10:

(x - 4)^2 + (y + 10)^2 = 100
