What is the equation of the circle with a radius of 5 and center of (2, 3)?
A (x + 2)2 + (y + 3) = 25
B (x + 2)2 + (y + 3)2 = 5
OA
OB.

None of the above.

Step-by-step explanation:

The equation should be (x - 2)^2 + (y - 3)^2 = 25

The standard equation of a circle is:

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

where (a,b) are the coordinates of the center and r, the radius.

here the center = (2,3) hence a = 2 , b = 3 and r = 5
