If the central angle measures 60 degrees, divide the 360 total degrees in the circle by 60. Multiply this by themeasure of the corresponding arc to find the total circumference of the circle. Use the circumference to find the radius, then use the radius to find the area.

hey friend
The total area of a circle is πr2. The area of the sector can be obtained by multiplying the circle's area by the ratio of the angle and 2π (because the area of the sector is proportional to its angle, and 2π is the angle for the whole circle, in radians):
