Help with Area of a sector

Area 1 = 175.84
area 2 = 156.30

area 1: A=(pi)r^2 x 140/360
in this case we would use the degree of the entire circle and the degree of the sector since it is not given.

area 2: A=(pi)r^2 x 280/360
in this case we would use the degree of the entire circle and the degree of the sector since it is not given.

Ithink it is15not sure tho
