Is an arc a fraction of a circumference?
It is part of a curve. If that curve happens to be a circle, then it is a fraction of a circumference but it need not be.
A fraction of a circle's circumference is known as the?
An arc
What fraction of a circle is 15 degrees?
It is: 15/360 = 1/24 of a circle's circumference
What is a measure of an angle as a fractional part of a circle?
An arc is a fraction of its circumference
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

What fraction of the circle circumference is on the base of the parallelogram?
It should be an infinitesimally small fraction, since a circumference is a curve and the base of a parallelogram is a straight line.
To find arc length what do you need to multiply a circle's circumference by?
the fraction of the circle covered by the arc
What is a measure of an angle as a fractional part of a circle?
An arc is a fraction of its circumference
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 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) .
How do you find a circumference of a circle if the radius is a fraction?

How do you work out the area of a sector when given the length of the arc?
If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)
