Solved by pluggable solver: Calculate area of a sector

Angle at center described by an Arc
The angle described by an arc at center is 36 degrees.

Arc of a circle
The Area of Sector is given by formula

Conversion of angles from degrees to radian:
The relation between two units of angle measurement is :

2* rad = 360 degrees

Area of Sector when angle in radians is,

Hence, For a circle of radius 10 Area of sector is 31.4159265 when it subtends an angle of 36 degrees at center.
