Question

The length of an arc of ac cicle of radius 12 cm is 10 phy find the central angle of this arc.

Answer 1

Ans.

first tell what is meant by phy. here

Answer 2

Answer:

150 degrees

Step-by-step explanation:

angle=arc length/radius

        =10 pi/12=5 pi/6

since this value is in radian angle, to convert it into degrees, multiplying by 180/pi

angle=5*180/6=5*30

angle=150 degrees
