The area of a circle sector is given by the following equation:
Where 'r' represents the radius and 'A' represents the angle.
Then, just plugging our information in this equation we get the following:
And this is the area of the metal used.
Area = 96.0inĀ²
Now, for the arc length, we have the following formula:
Again, just plugging our information:
Length = 19.2in
And this is our answer.
