Find the radian measure of the central angle

The radian measure of central angle is 0.8 radians

Solution:

Given that we have to find the radian measure of central angle

From given figure in question,

Arc length = 60 units

Radius = 75 units

The radian measure of a central angle θ of a circle is given as:

Where,

"r" is the radius of circle

"s" is the length of arc

= central angle in radians

Substituting the known values,

Thus radian measure of central angle is 0.8 radians
