*The arc length of a quarter circle can be found using the formula: Arc Length = (π/2) * radius. To calculate it, simply multiply π/2 by the radius of the quarter circle. This formula gives you the length of the curved boundary of a quarter circle, which is one-fourth of the circumference of the full circle.*
