brain cut an extra large round pizza into 12 pieceas .Seven of then were eaten. WQhay angle measure of pizza is left
a complete circle has 360 degrees.
So, 1/12 of a circle (a slice) has 30 degrees.
So, how many degrees in the 5 uneaten slices?
To find the angle measure of the pizza that is left, we first need to determine the total angle measure of the whole pizza.
When a pizza is cut into slices, each slice creates an angle at the center of the pizza. Since the pizza was cut into 12 pieces, it means there are 12 equal angles.
To find the measure of each angle, we divide the total angle at the center of the pizza (360 degrees) by the number of slices:
360 degrees / 12 slices = 30 degrees per slice
So, each slice has an angle measure of 30 degrees.
If seven out of the twelve slices were eaten, we need to calculate the total angle measure of the slices that were eaten.
7 slices * 30 degrees per slice = 210 degrees of pizza were eaten
To find the angle measure of the pizza that's left, we subtract the angle measure of the eaten slices from the total angle measure of the whole pizza:
360 degrees - 210 degrees = 150 degrees
Therefore, the angle measure of the pizza that is left is 150 degrees.
