Find the area of this circle. Use 3 for 1.
A = 7r2
3 ft
[?] ft

27ft²

Step-by-step explanation

Area of a circle = πr²

Given

radius r = 3 ft

Substitute r = 3 into the formula

A = π(3)²

A = 9π

A = 9(3)

A = 27ft²

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

ratio is 2 : 9

the answer is three

13.5 : 3
