Welcome, math enthusiasts and circle aficionados! Ever wondered how to calculate the perimeter of a quarter circle and didn’t know where to start? Fret not, we’ve got you covered. But remember, this isn’t a piece of cake – it’s a piece of pi!

The formula to calculate the perimeter of a quarter circle is quite straightforward. It’s simply the sum of the circle’s radius and one-fourth of its circumference. The circumference of a circle is calculated using the formula 2πr, where r is the radius. So, the formula for the perimeter of a quarter circle becomes:

```
Perimeter = r + (1/4) * 2πr
```
