WebFeb 2, 2024 · What is the radius of a circle? Circumference (blue) is the perimeter length of the circle. The diameter (red) is a line with both endpoints on the circle going through the center. Chord (purple) is any line with both endpoints on the circle. A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius. Usually, the radius is required to be a positive number. A circle with (a single po…

WebFeb 3, 2024 · 2. Divide the diameter by two. A circle's. radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm. In math formulas, the radius is r and the diameter is d. You might see this step in your textbook as. r = d 2 {\displaystyle r= {\frac {d} {2}}} . WebNow we draw a 45° angle on the two circles, as in Figure 13. Figure 13 A 45° angle contains one-eighth of the circumference of a circle, regardless of the radius.
