Answer
$(x-2)^2+(y+5)^2+(z-3)^2=25$
Work Step by Step
To solve this problem let us look at the formula given. We simply have to plug in our coordinates of our center and the value of the radius in place of a,b,c, and r. r is 5 and $(a,b,c)$ is $(2, -5, 3)$. Plugging that in we get $(x-2)^2+(y+5)^2+(z-3)^2=25$
