Point
the circle below is centered at (-1, 1) and has a radius of 3. what is its
equation?

(X + 1)² + (Y - 1)² = 9

Step-by-step explanation:

Given as the center of circle as ( -1, 1)   and radius as 3 unit

Now standard equation of circle with center and radius is

(X - a)² + (Y - b)² = r²   , where center is (a ,b)  with radius r

so, (X + 1)² + (Y - 1)² = 3²

Or, (X + 1)² + (Y - 1)² = 9  Hence this is required circle equation . Answer

16.80 times .20= 3.36
