Radius Symbol r

Radius Symbol assigns r to mathematical notation. For Radius Symbol, formulas, codes, styled letters, and fields that give r another role remain separate. For Radius Symbol, r is encoded as U+0072, and its Unicode name is LATIN SMALL LETTER R. The text form documented under Radius Symbol is r. Before changing the character, inspect the intended convention. The approved formatting approach includes In equations, define r as Radius Symbol before relying on the character alone. It also includes Preserve the complete sequence U+0072; do not remove spaces, component letters, superscripts, joiners, or variation selectors. Preserve searchability and selection unless an image is essential. When an HTML representation is needed, use r directly or the recorded numeric forms, including r and r. The source domains include unicode.org, dlmf.nist.gov, nist.gov. For copy-and-paste validation, the strongest samples are “Radius Symbol: r”; “Equations — r”; “Proofs: Radius Symbol r”. They place the symbol in equations, proofs, worksheets instead of leaving it semantically unsupported. r commonly represents a radius, but geometry and physics sources may use R or a subscripted form. The letter alone is not exclusive to radius; the diagram, formula, and definition establish the intended quantity. Examples for Radius Symbol include Radius Symbol: r; Equations — r; Proofs: Radius Symbol r; r radius symbol reference. For Radius Symbol formatting, In equations, define r as Radius Symbol before relying on the character alone; Preserve the complete sequence U+0072; do not remove spaces, component letters, superscripts, joiners, or variation selectors; Compare r with ∈ and ≈ before selecting a visually similar form.
