Let us draw a circle with radius = 6 cm with centre O. 2. Position a point P, which is 10 cm away from O. The circumference of a circle can be obtained by using the equation below: where the mathematical constant, , has a value of approximately 3.14 and r represents the radius of the circle. = 5 cm. Measure Angles.. Find an answer to your question unit 10: Assume that segments that appear to be tangent are tangent. Definition. Radius is the shortest word and shortest measure; Diameter is longer; Circumference is the longest; Definition : The circle is a plane shape (two dimensional), so: Circle: the set of all points on a plane that are a fixed distance from a center. is a button on your calculator you can find, but is also generally known as 3.14, you can use either one, but teachers usually prefer you use the button. A radius is the distance from the center of the circle to its boundary line. All radii of the same circle are equal to each other. A chord is a line between any two points on the outer line of the circle. A diameter is a chord that passes through the center. It is also the longest chord. The diameter measures two radii. Find each value and measure. Now, imagine your square is made up of smaller unit squares. It depends on how precise you can measure the radius. Construct a pair of tangents to it, the angle between which is 60^0 . Now draw segment AC, to form inscribed angle BAC, which intercepts the same arc as central angle BOC. Given the diameter or radius of a circle, we can find the circumference.
