Answer:
![452\ ft^{3}](https://tex.z-dn.net/?f=452%5C%20ft%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
![V=\pi r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7D%20h)
we have
----> the radius is half the diameter
substitute the values
![V=(3.14)(6^{2})(4)=452\ ft^{3}](https://tex.z-dn.net/?f=V%3D%283.14%29%286%5E%7B2%7D%29%284%29%3D452%5C%20ft%5E%7B3%7D)
Answer:
44
Step-by-step explanation:
these triangles are similar, so the proportions of the sides will be the same. Since the small triangle's proportions are 4:4, the bigger one's will be 44:44
Answer:
Step-by-step explanation:
15²+20²=225+400=625
22²=484
15²+20²≠22²
it is not a right angled triangle.
not all sides equal so not an equilateral triangle.
No two sides are equal .
it is not an isosceles triangle.
it is scalene.
