A lunette is a semicircular window that is sometimes placed above a doorway or above a rectangular window. A certain lunette has a diameter of 40 in. To the nearest square inch, what is the area of the lunette?

The area of the lunette is ≈
in2.

628 in²

Step-by-step explanation:

Radius = 40/2 = 20 in

Area = ½ × pi × r²

= ½ × 3.14 × 20²

= 628 in²

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
