Calculate Radial Distance







Formula

The formula to calculate the Radial Distance (Drad) is:

\[ D_{rad} = \sqrt{(X_2 - X_1)^2 + (Y_2 - Y_1)^2} \]

Where:

Example

Let's say the internal point is (3, 4) and the point along the radius is (7, 1). Using the formula:

\[ D_{rad} = \sqrt{(7 - 3)^2 + (1 - 4)^2} \]

We get:

\[ D_{rad} = \sqrt{16 + 9} = \sqrt{25} = 5 \]

So, the radial distance is 5 units.
