For a circle w/radius 55.5cm
A=π*55.2²
44.4º is 44.4/360 of a circlw so
A=π*55.5²*44.4/360
A=1193.4831951171284768088620646994 cm² round to
A=1193 cm²

Area = π r² (44.4/360)

44.4/360 is ratio of the sector area to the complete circle area.

Area = π (55.5)² (44.4/360)

Area = 1,193 cm²
.

A = πr² First get the area of the entire circle, and multiply that by (195/360) to get just the segment. .
