Answer:
36π inches
Step-by-step explanation:
Formula for the area of a circle is A = π r^2
Plug in 6 for r into the equation. A = π 6^2
A = 36π
To calculate the IQR, we need the radian, which is the middle number of each column, namely (86,82) for each exam.
Above the middle number, we have 5 values. The middle value (of the upper part) is Q3, which is on the third line, or (92,85).
Below the middle number, we also have 5 values. The middle (of the lower half) is Q1, which is on the 9th line (80,78)
The IQR is the difference between Q3 and Q1, namely
(92-80, 85-78) = (12, 7)
Since 12>7, we conclude that the IQR of the mid-term is higher than the final.
The mean of a set of numbers is the sum divided by the number of terms.So, 20+24+12+44+68 / 5
mean = 33.6
