If you mean a pie graph, then it is necessary to now the total number that is represented by the whole pie.
The full circle graph covers 360 degrees, just like any other circle. 9% = 0.09 9% of 360 degrees = 0.09 x 360 = 32.4 degrees
Degrees are used to measure the arc of a circle. A full circle is 360 degrees, and a half circle 180. so 9 degrees would be 1/40th of a complete circle.

Draw a circle with its center at the origin and a radius of 3.
Draw radius lines 40 degrees apart. 360 degrees divided by 9 = 40

If everything to the left of -9 on a graph is shaded, the inequality represented is ( x < -9 ). This means that all values of ( x ) that are less than -9 are included in the solution set. The shaded region on the graph indicates that the inequality does not include -9 itself, which is typically represented by an open circle at that point.
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
