Given the measure of central angle at 6°, find the number of sides, n:
 
     n = 360° ÷ 6°
     n = 60 

Sum of interior angles
     = (n-2) (180°)
     = (60 - 2) (180°)
     = (58) (180°)
     = 10,440°

Number of diagonals
     =  \frac{n (n-3)}{2}
     =  \frac{60 (60-3)}{2}
     = (30) (57)
     = 1,710
