Step-by-step explanation:
General formula for the area of a circle = πr^2.
Since the diameter is 8, the radius is 4 (half of diameter)
So the area is π(4)^2 = 16π.
Answer:
D
Step-by-step explanation:
Hi! I think I understand the question.
The error in the plot is the median and the lower quartile.
From smallest to largest, these are the numbers with the median, lower quartile, and upper quartile are pointed out:
3,3,4| 4.5 |4,5,5| 5.5 |6,7,7| 7.5 |8,8,9
As you can see above, the correct median and lower quartile are 5.5 and 4.5. In your plot, the median and lower quartile are 6 and 4.
I hope this helped and I hope you're feeling better. :)
|x| means the absolute value of x and removes any negatives. So |14| = 14 and |-14| = 14 meaning the answer is D.
