The length of AB the minor arc is 40 cm What is the circumfe

The length of AB (the minor arc) is 40 cm. What is the circumference of C? A. 240 cm B. 24 cm c. 6.67 cm D. 120 cm E. 360 cm F. 60 cm

Solution

The length of minor arc AB is 40

Angle subtended by the arc AB is 60

Hence the angle is 1/6 of total angle360

Therefore the total circumfrence is 6 times length of AB

=6*60

=360
