The circumference of the circle is 23 inches what is the radius of the circle?

The radius is 3.66 if you need to round it would be 3.70.

Step-by-step explanation:

r= c/2

23/2pi= 3.66

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
