We find the area of the smaller circle and subtract from the area of the larger circle.
Area of smaller circle is
Area of larger circle is
The area of the shaded region is:
Let width be x
3x= length
Knowing that 9=x
Area=lw
A= 9(3 x 9)
a= 243 ft

Answer: D) All real numbers greater than or equal to -4.
Explanation:
The lowest point occurs when y = -4, which is where the vertex is located.
The range consists of y values such that y = -4 or y > -4. We can shorten that last sentence to say . So y is greater than or equal to -4.
As you can probably tell, the range is the set of all possible outputs of a function.
