How To Find A Radius For Hollow Objects? The radius of a sphere or a circle is the distance from its center to its circumference. For any regular polygon, the radius is the same from the center to all its vertices. A circle is a regular polygon where the distance from the center to ...
The formula to find the arc length of a sector is as follows: {eq}s=r\theta {/eq}, where you would need the length of the radius between the endpoint of the arc and the center of the circle, and the angle's measure in radians. How do you find arc length with angle and radius...
