Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length Radius r Arc Length s 45 kilometers 85 kilometers rad

Solution

S= r*(theta)

S= arc length

r= radius

Theta= angle in radians

Here given both s and r in same units so we should take radians

Theta =( s/r) = (85/45)=(17/9)
