Answer:
1985 cubic units (written as un. with the cubed exponent)
Step-by-step explanation:
First, you find the volume of the cylinder
Here's the formula:
![V=\pi r^{2}h\\V=volume\\r=radius\\h=height](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7Dh%5C%5CV%3Dvolume%5C%5Cr%3Dradius%5C%5Ch%3Dheight)
Now, you plug in and solve.
![V=(3.14)(7.2^{2})(7.4)\\V=(3.14)(51.84)(7.4)\\V=(162.7776)(7.4)\\V=1204.55424\\rounded:\\V=1204.6](https://tex.z-dn.net/?f=V%3D%283.14%29%287.2%5E%7B2%7D%29%287.4%29%5C%5CV%3D%283.14%29%2851.84%29%287.4%29%5C%5CV%3D%28162.7776%29%287.4%29%5C%5CV%3D1204.55424%5C%5Crounded%3A%5C%5CV%3D1204.6)
Then, you find the volume of the dome.
Here's the formula:
![volume/of/a/sphere=\frac{4}{3}\pi r^{3}\\volume/of/a/dome:\\V=\frac{2}{3}\pi r^{3} \\V=volume\\r=radius](https://tex.z-dn.net/?f=volume%2Fof%2Fa%2Fsphere%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D%5C%5Cvolume%2Fof%2Fa%2Fdome%3A%5C%5CV%3D%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E%7B3%7D%20%5C%5CV%3Dvolume%5C%5Cr%3Dradius)
Now, you just plug in and solve.
![V=(\frac{2}{3})(\pi)(r^{3})\\V=(\frac{2}{3})(3.14)(7.2^{3})\\V=(\frac{2}{3})(3.14)(373.248)\\V=(2.093)(373.248)\\V=781.208064\\rounded:\\V=781.2](https://tex.z-dn.net/?f=V%3D%28%5Cfrac%7B2%7D%7B3%7D%29%28%5Cpi%29%28r%5E%7B3%7D%29%5C%5CV%3D%28%5Cfrac%7B2%7D%7B3%7D%29%283.14%29%287.2%5E%7B3%7D%29%5C%5CV%3D%28%5Cfrac%7B2%7D%7B3%7D%29%283.14%29%28373.248%29%5C%5CV%3D%282.093%29%28373.248%29%5C%5CV%3D781.208064%5C%5Crounded%3A%5C%5CV%3D781.2)
Finally, you add them together, and there's your answer!
![1204.6+781.2=1985.8](https://tex.z-dn.net/?f=1204.6%2B781.2%3D1985.8)

Answer:
25%
Step-by-step explanation:
The discount was $2.50. Dividing $2.50 by $10, we get 0.25, or 25%
Answer: 0p + 40
Step-by-step explanation:
5p + 30 - 5p + 10
0p + 40
<span>length of finger nail in m month =10+3m
length of finger nail in 8 months =10+3*8
=10+24 =34mm
I think thats the answer but im pretty sure thats the answer </span>
Answer:
50 times
Step-by-step explanation:
You are going to flip a coin 100 times. There are 2 sides. So, what you would do is divide 100 by two because there are two sides. There is a 50% chance that the coin will land on heads, and a 50% chance it will land on tails.
Please let me know if you have any more questions. Hope this helps!
