Given the center
and the radius
of a circle, its equation is

In your case, the center is (-4,0), and the radius is 2. Plug these values into the generic formula and you'll get the equation.
Answer:
Step-by-step explanation:
(1). A = π r²
A = 4 π
Area of shaded region is
=
or
(2). C = 4 π
In this case, the length of the bigger arc and the area of shaded region happen to be the same.
The length of the arc ADB is
or
Using proportions, it is found that the Customer Acquisition Cost was of $1,215.
<h3>What is a proportion?</h3>
