The 18 pages that link to Radius, each with the reason it gives.

• CircleRelated: Every point on a circle lies one radius from its center.

• RadianRelated: The radius is the denominator in the arc-length ratio that defines radians.

• SphereRelated: The radius is the fixed distance that determines the sphere.

• Centrifugal forceRelated: Centrifugal force grows in direct proportion to distance from the rotation axis.

• Great circleRelated: The radius fixes the great circle’s radius and helps define its central angles.

• Inscribed angle theoremRelated: Equal radii create the isosceles triangles used in a standard proof.

• DiameterRelated: A diameter consists of two radii joined end to end through the center.

• Central angleRelated: Each side of a central angle lies along a radius.

• Centripetal accelerationRelated: A larger radius means less centripetal acceleration at the same speed.

• ChordRelated: Radii drawn to a chord’s endpoints form an isosceles triangle.

• ConeRelated: The base radius helps determine the cone’s volume and slant height.

• Unit sphereRelated: The unit sphere is distinguished from other concentric spheres by its radius of one.

• Wheel and axleRelated: The wheel and axle radii determine their relative travel and force.

• Tangent–secant theoremRelated: A radius to the point of tangency is perpendicular to the tangent line.

• Descartes' theoremRelated: Curvature is defined as the reciprocal of each circle's radius.
