I cant find this problem anywhere else, so here.

What is the number of units in the area of the circle with center at $P$ and passing through $Q$? Express your answer in terms of $\pi$

radius of circle  =  distance between  (-3, 4)  and  (9, -3)

 

radius of circle   =   \(\sqrt{(-3-9)^2+(4--3)^2}\)

 

radius of circle   =   \(\sqrt{193}\)

 

area of circle   =   pi * ( radius )2

 

area of circle   =   \(\pi\cdot(\sqrt{193})^2\)

 

area of circle   =   \(193\pi\)

Yes. That is correct. Thank you.
