Answer:
If you know the radius, r, of the circle and you know the central angle, ϴ, in degrees of the sector that contains the segment, you can use this formula to calculate the area, A, of only the segment: A = ½ × r^2 × ((π/180) ϴ - sin ϴ)

Answer:
9.425
Step-by-step explanation:
Formula for finding area of circle A=r^2 * pi * subsent angle / 360;
A = 6cm^2 * pi * 30 / 360= 36 * pi / 12 = 3 * pi = 9.425.
