( x - 10 )^2 + (y - 10 )^2 = 144 (x10)2+(y10)2=144

Explanation:

The standard form of the equation of a circle is :

(x - a )^2 + (y - b )^2 = r^2 (xa)2+(yb)2=r2

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

here the centre is (10 , 10 ) and r = 12

substitute these values into the standard form to obtain equation.

rArr (x - 10 )^2 + (y - 10 )^2 = 144(x10)2+(y10)2=144
