What is the radian measure of the central angle of an arc that has an arc length of 5 units and radius of 2 units

Central angle = θ = 2.5 radians

Step-by-step explanation:

The radian measure of central angle is given by

Where s is the arc length, r is the radius of circle and θ is angle in radians

We are given an arc length of 5 units

We are given radius of 2 units

Therefore, the central angle in radians is

Bonus:

Radian is a unit which we use to measure angles.

1 Radian is the angle that results in an arc having a length equal to the radius.

Degree is another unit that we use to measure angles.

There are 360° in a circle.

There are 2π radians in a circle.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
