Convert Cartesian coordinate into polar coordinate
(2,2)

Explanation

To convert the Cartesian coordinates (2, 2) into polar coordinates, we will follow these steps:

### Step 1: Identify the Cartesian coordinates
The given Cartesian coordinates are \( (x, y) = (2, 2) \).

### Step 2: Calculate the radius \( r \)
The formula for calculating the radius \( r \) in polar coordinates is:
\[
