A fraction circle is what is used to compare two different fractions using triangles.
For example if you have 4/8, 2/4 and 1/2 the answer is that they are equal.
The area of a sector is the area of the circle multiplied by the fraction of the circle covered by that sector. This is a true statement and correct formula.
one third
It means to circle the fractions that have the same values
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)
An arc
Half.

Well, honey, if you can't see that it's a half-shaded circle, then I don't know what to tell you. Half of the circle is shaded, which means it's a 1/2 fraction. So, grab a ruler if you need to, but trust me, it's half.
1/2 ===

A half.
An arc
To determine the fraction of a circle that 100 degrees represents, we need to consider that a full circle is 360 degrees. Therefore, we can calculate this as a fraction by dividing the given angle (100 degrees) by the total degrees in a circle (360 degrees). This gives us the fraction 100/360, which simplifies to 5/18. So, 100 degrees represents 5/18 of a circle.
There are 360 degrees in a circle so 45 degrees is 1/8th of a circle.
