Find the area.

Step-by-step explanation:

You know that both figures are similar. So, in order to find the missing area, you need to follow these steps:

1. You must find the scale factor of the the perimeter of the smaller figure to the  perimeter of larger figure. This is the ratio between the perimeters. Since it is a lenght, you know that:

2. Now, you must find the scale factor  of the area of the smaller figure to the area of the larger figure. This is:

3. Set up the following proportion:

4. Finally, you must solve for "A", which is the area of the larger figure:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

the radius is 2 times the diameter.
