Answer:
The volume of a cylinder is 5091.43 cm³.
Step-by-step explanation:
The volume of a cylinder is:
![V=\pi\ r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cpi%5C%20r%5E%7B2%7D%20h)
From the information provided it can be concluded that:
The height of the cylinder is, <em>h</em> = 20 cm.
The radius of the base is, <em>r</em> = 9 cm.
Compute the volume of a cylinder as follows:
![V=\pi\ r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cpi%5C%20r%5E%7B2%7D%20h)
![=\frac{22}{7}\times 9^{2}\times 20\\\\=\frac{22\times 81\times 20}{7}\\\\=5091.42857\\\\\approx 5091.43](https://tex.z-dn.net/?f=%3D%5Cfrac%7B22%7D%7B7%7D%5Ctimes%209%5E%7B2%7D%5Ctimes%2020%5C%5C%5C%5C%3D%5Cfrac%7B22%5Ctimes%2081%5Ctimes%2020%7D%7B7%7D%5C%5C%5C%5C%3D5091.42857%5C%5C%5C%5C%5Capprox%205091.43)
Thus, the volume of a cylinder is 5091.43 cm³.
V= 1/3AH, thats the formula
