# (x -2)^2 + (y - 5 )^2 = 9#

#### Explanation:

The standard form for the equation of a circle is.

# (x - a )^2 + (y - b)^2 = r^2 # where (a , b ) is the centre and r , the radius.

This question gives all the necessary information needed to

complete the equation , centre = (2 , 5 ) and r = 3

hence equation is :

#(x - 2)^2 + (y - 5 )^2 = 9#
