**Step 1: Write down relevant formulas**  
For a circle with radius $$ r $$, the formulas are:  
- **Perimeter (Circumference):**  
  $$
  C = 2\pi r
  $$  
- **Area:**  
  $$
  A = \pi r^2
  $$

**Step 2: Substitute the radius (if known)**  
If a specific radius is given (say $$ r = r_0 $$), substitute into the formulas:  
- **Perimeter:**  
  $$
  C = 2\pi r_0
  $$  
- **Area:**  
  $$
  A = \pi {r_0}^2
  $$

**Step 3: Conclude the solution**  
The perimeter (circumference) of the circle is $$ 2\pi r $$ and the area is $$ \pi r^2 $$.  
If the radius is specified, plug in its value to compute the numerical results.
To find the perimeter and area of a circle, use the formulas: - **Perimeter (Circumference):** $$ C = 2\pi r $$ - **Area:** $$ A = \pi r^2 $$
