Which is an equation of a circle with center (2, -10) and radius 3?

A. (x - 2)2 + (y + 10)2 = 9
B. (x + 10)2 + (y - 2)2 = 9
C. (x - 2)2 + (y + 10)2 = 3
D. (x + 2)2 + (y - 10)2 = 3

Answer 1

okay ready

Answer 2

yes

Answer 3

okay any circle with center (a,b) and radius r has the equation (x-a)^2 + (y-b)^2 = r^2
if you think about it, you will see why this is obvious if you thinking about points on the circle and what its distance from the center should be

here (x-2)^2 + (y+1)^2 = 9
