<span>A polygon that is sometimes regular is a pentagon. A regular polygon is a polygon that has all sides equal and all interior angles are equal. Its sides and vertices are evenly spread around a central point, and a regular polygon is called convex where all the vertices point “outwards”.</span>
Answer:
8.6 in²
Step-by-step explanation:
The area of the entire circle is A = πr², or A = π(2 in)².
This corresponds to a central angle of 2π radians, or 6.28 radians.
The area of the sector described above is just a certain fraction of that:
4.3 rad
-------------- * Area of circle = 0.685(4 * 3.14) = 8.6 in²
6.28 rad
