If the length of the shorter arc AB is 22 cm and C is the centre of the circle then the circumference of the circle is?

The arc covers 45 degrees of the 360 degree circle or   45/36o fraction of the entire circle

 

45/360 * x = 22            where x is the total circumference

 

x = 22 * 360/45 = 176 cm
