The value of r represents the directed distance when plotting a point in polar coordinates. a. true b. false

The given statement is a TRUE statement.

Step-by-step explanation:

In polar coordinates i.e. (r,θ); r represents the polar distance and θ represents the polar angle.

A point in the plane is at a distance 'r' from the origin and the angle 'θ' is the distance between the line drawn from origin to a point at a distance r and the x-axis.

Hence, The value of r represents the directed distance when plotting a point in polar coordinates.
