Answer:
Which problem?
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:

Hence, both ratios are equal to each other
Answer:
D 81 pi units^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
18 pi = 2 * pi *r
Divide each side by 2 * pi
18 pi / (2 pi) = 2 pi * r/ (2 pi)
9 = r
Now we can find the area. Area is given by
A = pi r^2
A = pi * 9^2
A = 81 pi units^2
The number of data values between the lower quartile and the median is less than the number of data values between the upper quartile and the median.
Hope this helps!
