The diagram shows a sector of a circle, centre O and radius 6 cm.
The sector angle is 30 degrees.
The area of the shaded segment is (kπ - c) cm^2, where k and c are integers.
Find the value of k and the value of c.
I know the solution and I know the area of the shaded area but I don't know how to get k and c...

Answer:
k = 3
c = 9
Step-by-step explanation:
Area of Shaded region = Area of sector - area of triangle
Area of sector = (30/360)πr²
= (1/12)π6²
= 3π cm²
= 9 cm²
Area of Triangle = (1/2) * 6 * 6 Sin30
= 18 *(1/2)
= 9 cm²
Area of Shaded region = 3π - 9 cm²
(kπ-c) cm²
k = 3
c = 9
