Mary has a small round mirror in her purse. if the mirror is 4 inches in diameter, what is the area of the mirrored surface?

Diameter = 4 inches

Radius = diameter/2 = 4/2 = 2 inches

Area = πr^2 = π(2)^2 = 4π = 12.57 inches squared approx.

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
