9. use the given information to write the standard equation of
the circle.
the center is (2, 2). a point on the circle is (5, 6).
[a] (x - 2)² +(y-2)2 = 49
[b] (x - 2) +(y-2)² = 25
[c] (x + 2)² + (y + 2)° = 25
[d] (x - 2) +(y-2)² = 5

(x-2)²+(y-2)²=25

Step-by-step explanation:

find out radius' square first

r² = (5-2)²+(6-2)²

r²= 25

so the equation is

(x-2)²+(y-2)²=r²=25
