Question

The length of an arc of a circle of radius 12 cm is 4π cm. Find the central angle of this arc​

Answer 1

Step-by-step explanation:

given :length of arc =4πcm and radius =12cm

find :central angle of arc

length of arc = theta /360*2πr

4π = theta /360 *2*π*12

4π =theta /360*24π

1/6 =theta /360

on cross multiplying

6 theta =360 degree

theta =360/6

theta =60degree

hence, the central angle of this arc is 60 degree

Answer 2

Answer:

60°
