any ideas @wolf1728 ?

wolf1728 · Answer

Circle area = PI * r²
Circle area = PI * 109.9²
Circle area = 37,944.19
Sector area = 29.4
Sector Area / Circle Area = 0.0007748222
Central Angle (degrees) = 0.0007748222 * 360
Central Angle (degrees) =0.2789360031
Central Angle (radians) = 0.0048683517
that's a REALLY small angle
