How do you find the area of circle #(x - 4)^2 + (y - 2)^2 = 9#?
This is an equation of a circle in standard form. The equation
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
From the equation of the circle, we can see that
#A=pir^2" "=>" "A=pi(9)" "=>" "A=9pi#
