Check the picture below.
notice, is just a circle inscribed in a square.
now for the first one, we know the diameter is 14, so the square is a 14x14, and the radius of that is half the diameter or 7.
now, if we get the area of the square, which includes the area of the circle, and THEN get the area of the circle and subtract it from the square's, what's leftover is the shaded section.
![\bf \textit{area of a circle}\\\\ A=\pi r^2\\\\ -------------------------------\\\\ \stackrel{\textit{square's area}}{14\cdot 14}~-~\stackrel{\textit{circle's area}}{\pi 7^2}\implies 196-49\pi](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Barea%20of%20a%20circle%7D%5C%5C%5C%5C%20A%3D%5Cpi%20r%5E2%5C%5C%5C%5C%0A-------------------------------%5C%5C%5C%5C%0A%5Cstackrel%7B%5Ctextit%7Bsquare%27s%20area%7D%7D%7B14%5Ccdot%2014%7D~-~%5Cstackrel%7B%5Ctextit%7Bcircle%27s%20area%7D%7D%7B%5Cpi%207%5E2%7D%5Cimplies%20196-49%5Cpi%20)
now, for the one on the right-hand-side, the radius is 8, and square's area is 16x16,
I'd say it would be less. (Not certain of a specific answer though)
4: line S could also be called UX (points that lie on the line)
5: Q,T,P (these points all lie in plane K)
6: T,R,Y (these points all lie in line TY)
7: Q,T,P (other than given name K, you can name a plane using 3 coplanar points. we use the same answer as 5 because that question already asked us to find 3 coplanar points)

I thought this was going to be easy been sitting here for 20min
Answer:
No
Step-by-step explanation:
A matched pair design is used when we have two different observation about a certain experiment for each subject such that there is a natural pairing between the two population.
In the scenario described above, we have 20 subjects of which 10 are boys and 10 are girls.
Matching boys and girls having similar numbers does not depict natural pairing and thus using a matched paired test would be inappropriate. The test to use for such experiment is the two population t test.
