=(3x-2)(3x+7) is your final answer. Hope it help!
A cube because it’s already square n can be cut in square cross sections
Answer:
![525\pi](https://tex.z-dn.net/?f=525%5Cpi)
Step-by-step explanation:
Volume of a cylinder is given by the function ![v=\pi r^{2}h](https://tex.z-dn.net/?f=v%3D%5Cpi%20r%5E%7B2%7Dh)
where v is volume, r is radius and h is height.
In order to find the radius we just divide the diameter in half and get
![\frac{10}{2} =5=r](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B2%7D%20%3D5%3Dr)
now we just plug the values in the formula
![v=\pi r^{2}h\\=\pi (5^{2})(21)\\=\pi (25)(21)\\=525\pi](https://tex.z-dn.net/?f=v%3D%5Cpi%20r%5E%7B2%7Dh%5C%5C%3D%5Cpi%20%285%5E%7B2%7D%29%2821%29%5C%5C%3D%5Cpi%20%2825%29%2821%29%5C%5C%3D525%5Cpi)
