Answer:
V = 803.8 cm^3
Step-by-step explanation:
h = 12cm
r = 8cm
V =
![\pi](https://tex.z-dn.net/?f=%5Cpi)
h
V =
![\pi](https://tex.z-dn.net/?f=%5Cpi)
(12)
V = 4
(64)
V = 803.84
The function given is,
![f(x)=3x-1](https://tex.z-dn.net/?f=f%28x%29%3D3x-1)
a) Domain
This is the set of all points over which a function is defined.
Therefore, the domain of the function is
![-2\leq x\leq1](https://tex.z-dn.net/?f=-2%5Cleq%20x%5Cleq1)
b) Solving for the value of a
To solve for the value of a, the value of y = 0 at x = a
Therefore,
![\begin{gathered} f(x)=3x-1 \\ \text{where,} \\ f(x)=y=0 \\ x=a \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%28x%29%3D3x-1%20%5C%5C%20%5Ctext%7Bwhere%2C%7D%20%5C%5C%20f%28x%29%3Dy%3D0%20%5C%5C%20x%3Da%20%5Cend%7Bgathered%7D)
Solving for a
![\begin{gathered} 0=3(a)-1 \\ 0=3a-1 \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%200%3D3%28a%29-1%20%5C%5C%200%3D3a-1%20%5C%5C%20%20%5Cend%7Bgathered%7D)
Collect like terms
![\begin{gathered} 3a=0+1 \\ 3a=1 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203a%3D0%2B1%20%5C%5C%203a%3D1%20%5Cend%7Bgathered%7D)
Divide both sides by 3
![\begin{gathered} \frac{3a}{3}=\frac{1}{3} \\ a=\frac{1}{3} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B3a%7D%7B3%7D%3D%5Cfrac%7B1%7D%7B3%7D%20%5C%5C%20a%3D%5Cfrac%7B1%7D%7B3%7D%20%5Cend%7Bgathered%7D)
Hence,
Not saying my answer is 100% correct but I quickly tried to solve this and got 72.
