3 dni temu · The diameter of a circle is the length of a line that starts at one point on the circle, passes through the center and ends on another point on the circle's opposite side. It's also referred as the longest possible chord in the circle. The radius r r and the diameter d d are interrelated as. d = 2r. d = 2r. Circles - Circumference.
5 dni temu · Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle. In circle O, AD and BE are diameters.
4 dni temu · A line connecting any two points on a circle is called a chord, and a chord passing through the centre is called a diameter. The distance around a circle (the circumference) equals the length of a diameter multiplied by π (see pi). The area of a circle is the square of the radius multiplied by π.

5 dni temu · Study with Quizlet and memorize flashcards containing terms like How is the area of a semicircle found?, What part of the circumference is an arc whose measure is 30°?, What is the degree measure of an arc 4 ft. long in a circle of radius 10 ft.? and more.
5 dni temu · The general form of the equation of a circle is: x 2 + y 2 + 2gx + 2fy + c = 0. The center of the circle is (-g, -f). The radius of the circle is \(\sqrt{g^{2}+f^{2}-c}\). Calculation: We have, x 2 + y 2 - 4x - 4y + 4 = 0. On comparing it with the general equation of the circle, we get, g = -2, f = -2 and c = 4
