Step-by-step explanation:
Area of circle = pi x r^2 = 4 pi
So r^2 = 4
r =2
I think the orginal expression is -27z^2-4z^2

Answer:
The range is 19
Step-by-step explanation:
First, you have to order the numbers from least to greatest:
-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5
Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:
9.5 - (-9.5)= 19
So, the range is 19
