Circumference: The circumference is the distance around a circle. It can be calculated using the formula C = 2ฯr, where r is the radius.
Diameter: The diameter is twice the length of the radius. It is a straight line passing through the center of a circle or sphere and touching two points on its circumference or surface.
Arc Length: Arc length refers to a portion of a curve in a circle's circumference. It can be calculated using ฮธ/360ยฐ ร 2ฯr, where ฮธ represents an angle in degrees and r is the radius.
