The fraction of the circumference of a circle can be expressed in relation to its diameter. The circumference (C) is calculated using the formula C = πd, where d is the diameter. Thus, the fraction of the circumference to its diameter is π:1, meaning that for every unit of diameter, the circumference is approximately 3.14 times that length. This ratio is a fundamental property of circles.

How do you find the circumference of a circle when the raduis is a fraction?
The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
What fraction of a circle does 7 degrees represent?
It is NOT a fraction but a SECTOR. of 7 degres. The regions of a circle are: - Circumference ; all the way around. Radius ; distance from the centre to the circumference Diameter ; Twice the radius and a straight line from circumference through the centre to the opposite side . Chord; a line drawen inside a circle, betwwen two points on the circumference, but NOT touching the centre. Arc ; that part of the circumference that form the curved side of a sector. Sector ; An area inside the circle whose bondaries are two radii and an arc. Tangent ; a line outside the circle just touching the circumference in ONE place.
What is the circumference of a circle with radius 12cm in fraction?
The circumference of a circle is C = 2πr, where C is circumference, π is pi (3.14), and r is radius. C = 2 x 3.14 x 12cm = 75cm = 75/1 cm
How do you find a circumference of a circle that has a fraction as a radius?
The Circumference of a circle is twice the Radius x Pi (π) OR C = π x 2R ... (2 x Radius) x Pi (π) = Circumference The value of π is taken to be 3.142
How do you find the length of the arc of a circle with only the measurement of the central angle and the Circumference?
The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .
Define what the circumference of a circle?
The circumference of a circle is the distance around it.
