The area of the circular sector is calculated by the formula:
Ssec = pr: 2 * α / 360 °, where r is the radius of the given circle, α is the central angle of the sector.
Knowing the radius of the circle and the area of the sector, we can find the central angle:
α = Ssec * 360 / nr: 2 = 10 * n * 360 / n * 6: 2 = 10 * n * 360 / n * 36 = 100 °.
