He center of a circle represented by the equation (x + 9)2 + (y − 6)2 = 102 is

centre = ( - 9, 6)

the equation of a circle in standard form is

(x - a)² + (y - b)² = r²

where (a , b) are the coordinates of the centre and r is the radius

(x + 9)² + (y - 6)² = 102 is in this form

with centre = ( - 9 , 6 )

the answer is y = 11.54

hope this : )
