Answer:
A) h = 3V/ πr^2
Step-by-step explanation:
V = 1/ 3 πr^2h
Multiply each side by 3
3V = 3*1/ 3 πr^2h
3V = πr^2h
Divide each side by πr^2 to isolate h
3V /πr^2 = πr^2/πr^2 h
3V /πr^2 = h
Answer:
49.93
Step-by-step explanation:
it is 0.07 away from 50
Answer:
your answer is b 8/10 - 5/10
Step-by-step explanation:
First, you are going to want to get the terms to the same power of 10 in scientific notation. Realize that
. Essentially, we have converted the
to a term with
. Now, we can subtract the values in each term that are not 10 as shown below:
![93 \cdot 10^6 - 3.14 \cdot 10^6](https://tex.z-dn.net/?f=93%20%5Ccdot%2010%5E6%20-%203.14%20%5Ccdot%2010%5E6)
![(93 - 3.14) \cdot 10^6](https://tex.z-dn.net/?f=%2893%20-%203.14%29%20%5Ccdot%2010%5E6)
![89.86 \cdot 10^6](https://tex.z-dn.net/?f=89.86%20%5Ccdot%2010%5E6)
Remember that we have to turn it back to scientific notation once we are done!
![89.86 \cdot 10^6 = 8.986 \cdot 10^7](https://tex.z-dn.net/?f=89.86%20%5Ccdot%2010%5E6%20%3D%208.986%20%5Ccdot%2010%5E7)
Our answer is the second choice,
. (This is the closest answer to
.)
