Part C) The area of the rug is 
Step-by-step explanation:
Part A) Find the diameter of the rug
we know that
The circumference of a circle (circular rug) is equal to

where
D is the diameter
we have

we have


substitute

part C) What is the area the rug is covering?
The area of the circle (circular rug) is equal to

we have


substitute


A vertical stretch by a factor of 2 of F(x) = -2|x-2|+4 would result in the revised function G(x) = -4|x-2|+4. The vertex would stay in the same place (2,4).
