What is the measure (in radians) of central angle \thetaθtheta in the circle below?
Enter an exact expression.

Answer:
1 radians
Step-by-step explanation:
Here,
Arc length ( l ) = 8π cm
Radius ( r ) = 8 cm
To find : Angle θ ( in radians )
Formula : -
θ = l / r
θ = 8π / 8
θ = 1π
Note : -
Radians is denoted by " π ".
