#### Explanation:

This is an equation of a circle in standard form. The equation

#(x-h)^2+(y-k)^2=r^2#

describes a circle with its center at the point

Since we want to find the area of this circle, all we need concern ourselves with is the circle's radius, since the area of a circle can be found through the formula

#A=pir^2#

From the equation of the circle, we can see that

#A=pir^2" "=>" "A=pi(9)" "=>" "A=9pi#
