Answer:
A = 9 pi cm^2
Step-by-step explanation:
Circumference = 2 * pi *r
6pi = 2 * pi *r
Divide each side by pi
6 = 2r
Divide by 2
6/2 = 2r/2
3=r
Now we want to find the area
A = pi r^2
A = pi (3)^2
A = 9 pi cm^2
Since we are evaluating, we use PEMDAS so we know the order the operations. Follow PEMDAS:
Original Expression: (-1)8+(-1)7-16-14-(-1)2.
Evaluating: -8-7-16-14+2
-8-7=-15-16=-31-14=-45+2=-43.
The answer is -43 according to PEMDAS.

Step-by-step explanation:
Answer:
Area of the sector = 29.48 square miles.
Step-by-step explanation:
Given:
Radius of a circle = 13 miles
Angle bounded by the arc = 20 deg
To find
Area of the sector bounded by 20 degrees.
Note: Area of a sector =
Plugging the values in the equation.
⇒
⇒
⇒ square-miles
So the area of the sector bounded by 20 degree arc is 29.48 square miles.
