Find the sum of the interior angles and the number of diagonals of a regular polygon whose central angle is 6

The formula for sum of the interior angles is,

S = 180 x (n - 2)

and that of the number of diagonals is,

d = n x (n - 3) / 2

where n is the number of sides. For 6-sided polygon,

S = 180 x (6 - 2) = 720

d = 6 x (6 - 3) / 2 = 9

Therefore, the answer is 720 degrees and 9 diagonals.
