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.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
