What is the quarter circle's radius if the perimeter of a quarter circle is 32.13 centimeters?
The perimeter of a quarter circle is 2 radii plus a quarter of the circumference of the whole circle: → 2 × radius + ¼ × 2 × π × radius = 32.13 cm → radius × (2 + π/2) = 32.13 cm → radius = 32.13 ÷ (2 + π/2) cm ≈ 9.00 cm

How do you find the radius of a square?
A square does not have a radius. A square, with sides of length x units, can have an inscribed circle. Such a circle would have a radius of x/2 units. Or the square could have a circumscribing circle. This would have a radius of x/sqrt(2) units.
