**Step 1: Identify the Known Formulas**

For a circle with radius $$ r $$:
- The perimeter (circumference) is given by:
  
  $$
  C = 2\pi r
  $$

- The area is given by:
  
  $$
  A = \pi r^2
  $$

**Step 2: Substitute the Given Value**

If a specific radius is provided (for example, if $$ r = 5 $$), then substitute into the formulas.

For $$ r = 5 $$:
- Circumference:
  
  $$
  C = 2\pi (5) = 10\pi
  $$

- Area:
  
  $$
  A = \pi (5)^2 = 25\pi
  $$

If no specific value is given, the answers remain in terms of $$ r $$.

**Final Answers:**

- **General Form:**
  - Perimeter (Circumference): $$ C = 2\pi r $$
  - Area: $$ A = \pi r^2 $$

- **Example (when $$ r = 5 $$):**
  - Perimeter: $$ 10\pi $$
  - Area: $$ 25\pi $$
**Perimeter (Circumference):** $$ C = 2\pi r $$ **Area:** $$ A = \pi r^2 $$ *Example (when $$ r = 5 $$):* - Perimeter: $$ 10\pi $$ - Area: $$ 25\pi $$
