What is the equation of a circle with its center at (10,−4) and a radius of 2?
(x−10)2+(y+4)2=4
(x+10)2+(y−4)2=2
(x−10)2+(y+4)2=2
(x+10)2+(y−4)2=4

can someone please help i do not understand

Answered by david
the equation of a circle is (x-h)^2 + (x-k)^2 = r^2,
r = radius
h, k = x and y points of the center
you would plug in the center point coordinates into the circle equation to find your answer

therefore its B) (x+10)2+(y−4)2=2 :)
