Circle related formula
WebThe formula of radius of a circle is often denoted by “r”. There are different formulas for different events, much like: Radius = C/2π (for circumference), Radius = √ (A/π) (for area), Radius = D/2 (for diameter). Most circle related formulas, like circumference and area, are determined by first considering the radius.
