The quotient of the sum of a and b, and the product of a and b.

step-by-step explanation: i dont

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

a - base

b - exponent

so,

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
