sound like yu meen a serkel SEKTER. and the senter angel=2 radians.
1 radian=57.295779513082320 deg, so 2 rads=114.59155902616464 deg
distans along ark=22 inch....=radius*angel.
need tu get serkel radius (wide/2).
radius=(22 inch)/2=11 inch
sekter area=120.998354
triangel area=55.013179
segnent area=65.985174
ark hite=21.99970, triangel hite=5.94345, triangel wide=18.5122
