What is the approximate length of the minor arc 90 degrees 15cm?

To find the length of a minor arc, you can use the formula: ( L = \frac{\theta}{360} \times 2\pi r ), where ( \theta ) is the angle in degrees and ( r ) is the radius. For a 90-degree arc with a radius of 15 cm, the length is ( L = \frac{90}{360} \times 2\pi \times 15 ). This simplifies to ( L = \frac{1}{4} \times 30\pi ), which is approximately 23.56 cm.
