22= angle/360 × 2πr
22= angle/ 360× 2× 22/7 × 14
22= angle /360 ×88
22= angle/ 360 ×88
22/88= angle/ 360
1/4 = angle/ 360
Angle ×4= 360
Angle= 360/4
Angle = 90°
22= angle/ 360× 2× 22/7 × 14
22= angle /360 ×88
22= angle/ 360 ×88
22/88= angle/ 360
1/4 = angle/ 360
Angle ×4= 360
Angle= 360/4
Angle = 90°
