Question

Write the standard form of the equation of the circle shown in the graph

Answer 1

The general equation of a circle with center (h,k) and radius r is

(x-h)² + (y-k)² = r²

Here, the circle is centered at (3, -2) with radius 3 units.

So, the equation of given circle is

(x-3)² + (y+2)² = 3²=9

∴ (x-3)² + (y+2)² =9 is the required equation of the given circle.
