Find the approximate area of the shaded region of the figure below.
A: 489.44 cm2
B: 181.72 cm2
C: 27.86 cm2
D: 49.07 cm2

D:49.07

Step-by-step explanation:

The area of a rectangle is LxW and the area of a semi circle is (πr^2)/2

Because you are finding the area of the pieces around the semicircle, you would subtract the area of the semicircle from the area of the rectangle:

(LxW)-(πr^2)/2

Length=14cm, Width=9cm

R is the radius of the semicircle which is half the length, r=7cm

(14x9)-((π7^2)/2= 49.07

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.
