.

The area of a sector is equal


    area = %281%2F2%29%2Ar%5E2%2Aalpha 


where  r  is the radius and  alpha  is the central angle, in radians.


So, substitute the given numbers and calculate.


You are very lucky, since in this problem, the angle is just given to you in radians, 
so you DO NOT NEED to convert it from the degree measure to radians (!)
