Write the standard equation for the circle. center (-6 9) r=3 a. (x-9)^2+(y+6)^2=9 b. (x+6)^2+(y-9)^2=3 c. (x-6)^2+(y+9)^2=3 d. (x+6)^2+(y-9)^2=9 find the center and radius of the circle with equation (x+2)^2+(y+10)2=4 a. center (-2, -10); r=2 b. center (2, 10); r=4 c. center (-2, -10); r=4 d. center (10, 2); r=2 what is the equation of the fircle with center 3,5 that passes through the point (-4, 10)? a. (x-3)^2 + (y-5)^2 = 226 b. (x+4)^2 + (y-10)^2 = 74 c. (x+4)^2 + (y-10)^2 = 226 d. (x+3)^2 + (y-5)^2 = 74 what is the equation of the circle with center (0,0) that passes through the point (5,-4)? a. x^2 + y^2 = 41 b. (x+4)^2 + (y+4)^2 = 41 c. (x-5)^2 + (y+4)^2 = 9 d. x^2 + y^2 = 9
