Question

What is the measure (in radians) of central angle \thetaθtheta in the circle below?

Enter an exact expression.

Answer 1

1 radians

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 ".
