By definition, the area of a circle is given by:

Where,
r: radius of the circle.
Substituting the values in the given expression, we have:

Rounding to the nearest tenth we have:
Answer:
Approximately needed:
(n-2)*180=Sum of angle
(n-2)*180=2520
(n-2)=2520/180
n=14+2
n=16
Answer:
Option C. Independent Variable: time, Dependent Variable: net profit
Graph starts out rising and starts falling mid-year. At the beginning of 2006 it is at the minimum value and begins rising again before staying at a fairly constant rate for the remainder of the year
Step-by-step explanation:
In this problem
