Answer

$(x-3)^2+(y-2)^2=25$

Work Step by Step

RECALL: The standard equation of a circle whose center is at $(h, k)$ and has a radius of $r$ units is: $(x-h)^2 + (y-k)^2 = r^2$ The given circle has its center at $(3, 2)$ and a radius of 5 units. Thus, the standard form of the circle's equation is: $(x-3)^2+(y-2)^2=5^2 \\(x-3)^2+(y-2)^2=25$
