It is half the diameter.\n<ul class=\"wp-block-list\">\n<li><strong>Formula<\/strong>: Radius (r) = Diameter (d) \/ 2<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Diameter<\/strong>: The diameter is a straight line that passes through the center and connects two points on the circumference.

It can be measured in degrees.<\/li>\n\n\n\n<li><strong>Sector<\/strong>: A sector is a region of a circle bounded by two radii and the arc between them. It looks like a &#8220;slice&#8221; of the circle.<\/li>\n\n\n\n<li><strong>Segment<\/strong>: A segment is a region of a circle that is bounded by a chord and the arc connecting the endpoints of the chord.<\/li>\n\n\n\n<li><strong>Tangent<\/strong>: A tangent is a line that touches the circle at exactly one point. It is perpendicular to the radius drawn to that point.<\/li>\n\n\n\n<li><strong>Secant<\/strong>: A secant is a line that intersects the circle at two points.<\/li>\n<\/ol>\n\n\n\n<div
