Which of the following is the equation of a circle with a radius of 2.5 and its center at (4,- 3)?
(x - 4)^2 + (y + 3)^2= 2.5
(x - 4)^2 + (y + 3)^2= 6.25
(x - 4)^2 + (y- 3)^2= 2.5
(x - 4)^2 + (y - 3)^2= 6.25
(x - 4)^2 + (y + 3)^2= 2.5
(x - 4)^2 + (y + 3)^2= 6.25
(x - 4)^2 + (y- 3)^2= 2.5
(x - 4)^2 + (y - 3)^2= 6.25
