Answer:
that answer u put is correct and r u in K12 to lol
54 square inches
Basically you just multiply
Diameter is 9 inch so the radius is 9/2=4.5inch
Part A: 2πr=28.26inch
π=28.26/(2r)
π=28.26/(2*4.5)=3.14
Part B: πr^2=63.585inch
π=63.585inch/(4.5inch)^2
π=3.139753086
Part C: Both of the answers are correct but Part B is more percise because it has more significant figures.
Sure, depending on how the machine is constructed or programmed.
A function can represent any process that takes some input and assigns exactly one output to it. In the case of a simple vending machine, there could one button or sequence of button presses that correspond to the delivery of a certain drink or snack (provided that enough money is fed into the machine first).
A machine that wouldn't qualify as representing a function would be one that consistently offers two or more different drinks.
