<p>To find the length of OS in the given circle, we can follow these steps:</p><p><strong>Step 1: Understand the Geometry</strong> We have a circle with radius \( r = 10 \) cm. Chords PQ and PR each have a length of 12 cm. The line segment PO intersects
There are three circle radius formulas, depending on what number you know: The radius of a circle from the area: if you know the area A, the radius is r = √(A / π). The radius of a circle from circumference: if you know the circumference c, the radius is r = c / (2 ×π...
1. Draw the Circle and Chords: - Draw a circle with a radius of 2.5 cm. - Mark two parallel chords AB and CD such that the distance between them is 2.7 cm. 2. Identify the Midpoints: - Let M be the midpoint of chord AB and N be the midpoint of chord CD. - Since AB =...
