1) Identify the mean, median, and range of the data set below.
4, 8, 12, 15, 6, 9, 11
Mean:
Median:
Range:

Mean: 9.2857142857143

Median: 9

Range: 11

Step-by-step explanation:

The mean is the average of the data set. Add all the numbers up then divide by the amount of numbers you had to start with.

The median of a set of data is the middlemost number. Order your set into least to greatest order then count inwards. If you have an even set or number then add both middle numbers and divide by 2.

The range of a set of data is the difference between the highest and lowest values in the set. Find your lowest and highest value numbers and subtract the lowest number form the highest one.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
