Can I get the awnser to the problem?

452.4 ft^2

Step-by-step explanation:

A = pir^2

A = pi(12)^2

A = pi144

A is about 452.4

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

b. b < 1 might be the correct answer
