Circumference of a semicircle equation
WebFeb 22, 2024 · The formula is given as: Circumference of a circle = 2 (pi) (r) = (pi)d. where r is the radius of the circle, d is the diameter, and the value of pi is 3.14. The radius of a circle is a line segment that joins the center of the circle to any point on the circle’s circumference. It is half of the length of the diameter. WebFacts about Sector of a Circle. A section or part of a circle involved by two radii with a central angle $90^\circ$ is called a quadrant. A section or part of a circle involved by two radii with a central angle of $180^\circ$ is called a semicircle.
