Answer:
Formula for an opened end of a cylinder =
![\pi r^2 +2\pi rh\\](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%20%2B2%5Cpi%20rh%5C%5C)
Closed at both end =
![2\pi r^2 +2\pi r h](https://tex.z-dn.net/?f=2%5Cpi%20r%5E2%20%2B2%5Cpi%20r%20h)
Opened at both end =
![2\pi rh](https://tex.z-dn.net/?f=2%5Cpi%20rh)
Step-by-step explanation:
Step-by-step explanation:
<u>Step 1: Cross Multiply</u>
![\frac{3}{y} = \frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7By%7D%20%3D%20%5Cfrac%7B4%7D%7B5%7D)
![5(3) = 4(y)](https://tex.z-dn.net/?f=5%283%29%20%3D%204%28y%29)
![15 = 4y](https://tex.z-dn.net/?f=15%20%3D%204y)
<u>Step 2: Divide both sides by 4</u>
![15 / 4 = 4y / 4](https://tex.z-dn.net/?f=15%20%2F%204%20%3D%204y%20%2F%204)
![3.75 = y](https://tex.z-dn.net/?f=3.75%20%3D%20y)
Answer: ![y = 3.75](https://tex.z-dn.net/?f=y%20%3D%203.75)
Answer:
n= 75
y= 75
z= 50
p= 105
other n across from p= 105
Step-by-step explanation:
n and y are the same since the triangle is isoseles.
p is supplemetary to n
z and 50 are opposites in a quadrilateral
