A pizza is cut into 10 equal slices. What is the measure of each central angle (the part first eaten)?
how many degrees in a complete circle? 360
Divide that into 10 equal parts.
36
To find the measure of each central angle, we need to divide the total degrees in a circle by the number of slices.
The total degrees in a circle is 360 degrees because a circle is made up of 360 degrees.
In this case, a pizza is cut into 10 equal slices. Therefore, we divide 360 degrees by 10 to find the measure of each central angle.
360 degrees / 10 slices = 36 degrees
So, the measure of each central angle, or the part that is first eaten in this case, is 36 degrees.
