WebWhat is the Perimeter of Circle When Diameter is Given? If the diameter is given, the perimeter of the circle formula = πd. Where d is diameter and π is a constant with value (3.14 or 22/7). In terms of radius, the perimeter of the circle formula = 2 π r, where r is radius and value of D = 2r. WebTwo-dimensional figure measured in terms of radius. It is formed by a set of points that are at a constant or fixed distance from a fixed point in the center of the plane. The parts of the circle are circumference, radius, diameter, chord, tangent, secant, arc of a circle, and segment in a circle.
