Answer:
The amount of popcorn needed to fill the paper cone is ![V=1,005\ cm^{3}](https://tex.z-dn.net/?f=V%3D1%2C005%5C%20cm%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of a cone is equal to
![V=\frac{1}{3}\pi r^{2} h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7D%20h)
In this problem we have
![r=8\ cm](https://tex.z-dn.net/?f=r%3D8%5C%20cm)
![h=15\ cm](https://tex.z-dn.net/?f=h%3D15%5C%20cm)
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![V=\frac{1}{3}(3.14)(8)^{2}(15)](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%283.14%29%288%29%5E%7B2%7D%2815%29)
![V=1,005\ cm^{3}](https://tex.z-dn.net/?f=V%3D1%2C005%5C%20cm%5E%7B3%7D)
B because you multiply 7 times 4 that’s 28 then times 5 that’s 140 so for b you do 5 times 7 that’s 35 then times 4 that’s 140 so b is the correct answer, hope it helps
