The central angle is 2 radians.
Step-by-step explanation:
Arc length of circle = 6.9813
Radius of circle = 4
Central angle = ?
The formula used to find central angle is :

where s= arc length, r = radius and Ф= central angle
We are given:
s= 6.9813 and r = 4 , finding central angle:

Rounding off to nearest whole number:

So, The central angle is 2 radians.
