How would you find the fraction of a circle that an arc covers?
a. divide the measure of the arc by 180.
b. divide the circumference by 360.
c. divide the measure of the arc by 360.
d. divide the diameter by 360

Divide the measure of the arc by 360

Step-by-step explanation:

we can understand it with help of example.

Let there is a circle O in which An arc AC made a central angle 60°

Now the area in fraction = 60°/360°= 1/6

Because when we divide the circle in 6 parts then the area of each part = 1/6 of the area of the circle.

Therefore the central angle by this area is also 1/6 of the total central angle of the circle which is 360°

Thus, the angle made by this = 360°/6 = 60°

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.
