.

Smaller circles have radius 1 (they have a unit radius, as given in the problem).


Hence, greater circle has the radius of 2.


To complete the solution, from the area of the great circle subtract the area of two smaller circles


     -  =  -  =  = 6.28 square units (approximately).  ANSWER

Solved.
