WebJan 26, 2024 · Parts of a circle. A circle (the set of all points equidistant from a given point) has many parts, but this lesson will focus on three: Circumference – The distance around the circle (the perimeter of a circle). Diameter – The distance from the circle through the circle's center to the circle on the opposite side. (twice the radius) WebTherefore, the circumference circle equation is C = 2 πr. Example 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the formula πd to calculate the circumference.

WebA chord of a circle is a straight line segment whose endpoints both lie on a circular arc.If a chord were to be extended infinitely on both directions into a line, the object is a secant line.More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse.A chord that passes through a circle's center point is the circle's diameter.
WebDec 14, 2024 · To find the radius of a circle with a circumference of 10 centimeters, you have to do the following: Divide the circumference by π, or 3.14 for an estimation.
