I need HELP ASAP!! Please explain how to solve the problem

Step-by-step explanation:

The general format for the equation of a circle is the following:

Where is the center of the circle and () is the circle's radius. Please note, that the circle () has a center that is (h) units to the right of the origin, and (k) units above the origin.

The given circle has a center at , moreover, its radius is (3) units. Therefore, one must substitute these points into the equation of a circle and simplify to find its equation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
