Answer:
Therefore the volume of the cylinder is 5426 cm³.
Step-by-step explanation:
Shape is of Cylinder
Given:
height of a cylinder is 12 cm
diameter of the base of the cylinder is 24 cm
∴![Radius=\frac{Diameter}{2}=\frac{24}{2}=12\ cm](https://tex.z-dn.net/?f=Radius%3D%5Cfrac%7BDiameter%7D%7B2%7D%3D%5Cfrac%7B24%7D%7B2%7D%3D12%5C%20cm)
pi = Π= 3.14
To Find:
Volume of the cylinder in cubic centimeters = ?
Solution:
We Know that
![\textrm{ Volume of the cylinder }=\pi (Radius)^{2}\times Height](https://tex.z-dn.net/?f=%5Ctextrm%7B%20Volume%20of%20the%20cylinder%20%7D%3D%5Cpi%20%28Radius%29%5E%7B2%7D%5Ctimes%20Height)
On substituting the given values we get
![\textrm{ Volume of the cylinder }=3.14\times (12)^{2}\times 12\\\\\textrm{ Volume of the cylinder }=5425.92=5426\ cm^{3}](https://tex.z-dn.net/?f=%5Ctextrm%7B%20Volume%20of%20the%20cylinder%20%7D%3D3.14%5Ctimes%20%2812%29%5E%7B2%7D%5Ctimes%2012%5C%5C%5C%5C%5Ctextrm%7B%20Volume%20of%20the%20cylinder%20%7D%3D5425.92%3D5426%5C%20cm%5E%7B3%7D)
Therefore the volume of the cylinder is 5426 cm³.
Answer:
![\vec u+m\vec v=](https://tex.z-dn.net/?f=%5Cvec%20u%2Bm%5Cvec%20v%3D%3C8%2C14%3E)
Step-by-step explanation:
Being
=<3,4> and
=<1,2>, we must find
![\vec u+m\vec v](https://tex.z-dn.net/?f=%5Cvec%20u%2Bm%5Cvec%20v)
If m is the magintude of
:
![m=\sqrt{a^{2}+b^{2}}](https://tex.z-dn.net/?f=m%3D%5Csqrt%7Ba%5E%7B2%7D%2Bb%5E%7B2%7D%7D)
Where a and b are the components of ![\vec u](https://tex.z-dn.net/?f=%5Cvec%20u)
![m=\sqrt{3^{2}+4^{2}}=5](https://tex.z-dn.net/?f=m%3D%5Csqrt%7B3%5E%7B2%7D%2B4%5E%7B2%7D%7D%3D5)
![\vec u+5\vec v=+5=+=](https://tex.z-dn.net/?f=%5Cvec%20u%2B5%5Cvec%20v%3D%3C3%2C4%3E%2B5%3C1%2C2%3E%3D%3C3%2C4%3E%2B%3C5%2C10%3E%3D%3C8%2C14%3E)
