The interquartile range is 50.

Step-by-step explanation:

To find our answer we have to first quartile 1 and quartile 3 are equal too. When we look at the plot quartile 1  is equal to 20, quartile 3 is equal to 70 because it is in between 60 and 80.  Now to find the interquartile range we will subtract 70 from 20 and we get 50.  Therefore, 50 is our answer.

the answer could be 30

Step-by-step explanation:

look at the edges and find which number that is then you just subtract both numbers to get  the interquartile range (Q3 - Q1)

The answer is 24.84 because the formular for circumference is C=2(pi)r. So 2 times 3.14 times 6 which gives you 24.84
