Answer:
1.2
Step-by-step explanation:
Just keep adding 9 and keep track of your number. or just divide 9 and 300 or 3.
Answer:
Step-by-step explanation:
Let's start with the equation of the volume of a cylinder:
![V=\pi r^{2}*h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7D%2Ah)
Where:
- r is the radius of the cylinder (r=D/2=24/2=12 cm)
- h is the high of the cylinder (h = 60 cm)
We can us partial derivatives to find the differential of this volume. So we will have:
(1)
Now:
![\frac{\partial V}{\partial r}=2\pi r*h=2\pi 12*60=4523.9 cm^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpartial%20V%7D%7B%5Cpartial%20r%7D%3D2%5Cpi%20r%2Ah%3D2%5Cpi%2012%2A60%3D4523.9%20cm%5E%7B2%7D)
![\frac{\partial V}{\partial h}=\pi 12^{2}=452.4 cm^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpartial%20V%7D%7B%5Cpartial%20h%7D%3D%5Cpi%2012%5E%7B2%7D%3D452.4%20cm%5E%7B2%7D)
dr is a differential of the radius, so in our case it is 0.1 cm and dh, differential of the high, is 0.1*2 cm. We multiply by 2 because we need to consider the top and the bottom of the cylinder.
Now we just need to put all of this definitions in the equation (1).
I hope it helps you!
