Volume of Cylinder =
![\pi r^{2}h](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E%7B2%7Dh)
Based on what we're told:
r (radius) =
![\frac{s}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bs%7D%7B2%7D%20)
h (height) =
![s](https://tex.z-dn.net/?f=s)
So:
Volume of cylinder =
![\pi (\frac{s}{2})^{2}(s)](https://tex.z-dn.net/?f=%20%5Cpi%20%28%5Cfrac%7Bs%7D%7B2%7D%29%5E%7B2%7D%28s%29)

1.923 * 10 ^ -35 is the answer I got, however you did not specify any formatting to the question, so others may get a completely different answer
The books are $5, and the magazines are $10. I’m not sure which way you want it explained but since magazines are twice the price of books, you can solve the equation 3b + 2b = 25. This gives you b=5 which you just multiply by 2 giving you the price of a magazine.
Answer:
125 m
Step-by-step explanation:
The path of Kristina is in the shape of a right triangle where, the perpendicular is the path from the McDonalds to the three-way junction which is 145 m and the shortest distance between the McDonalds and the church is 191.442 m.
By Pythagoras theorem
![145^2+x^2=191.442^2\\\Rightarrow x=\sqrt{191.442^2-145^2}\\\Rightarrow x=125\ \text{m}](https://tex.z-dn.net/?f=145%5E2%2Bx%5E2%3D191.442%5E2%5C%5C%5CRightarrow%20x%3D%5Csqrt%7B191.442%5E2-145%5E2%7D%5C%5C%5CRightarrow%20x%3D125%5C%20%5Ctext%7Bm%7D)
Christina had to travel 125 m from the three-way junction to the church.
