pie*radius^2 (if you have the diameter half it to find the radius)
this will give the area of the circle (take pie as 3.142)

then go:

angle of sector (which sould be given) divided by 360 degrees
multiply this by the area of the circle

If the center angle of the sector is x its area is pi r^2 *x/360(x in degrees)
