One of the radii would be segment from (0,9) to (7,9). (Because circle is tangent to the y-axis from the description).
Radius is 7.

Equation for the circle, %28x-7%29%5E2%2B%28y-9%29%5E2=49

.
Center at (7,9), radius is 7 (since the circle is tangent to y-axis).


The standard form equation of this circle is


%28x-7%29%5E2+%2B+%28y-9%29%5E2 = 7%5E2,   or


%28x-7%29%5E2+%2B+%28y-9%29%5E2 = 49.

Find the standard form of the equation of the circle having the following​ properties:
Center at the point left parenthesis 7 comma 9 right parenthesis(7,9)
Tangent to the y dash axisy-axis
Find the equation yourself. FYI: The RADIUS is NOT 2 units. It's 7 units.

IGNORE anyone who says otherwise!
