The volume of the frustum is volume of the whole cone(A) minus the smaller cone(B) which is would give the volume of frustum(C) = 256cm³
<h3>Calculation of a frustum</h3>
The volume of cone A V=πr²h/3
Where radius = 20cm
The volume of cone B = V=πr²h/3
Where radius = 12cm
Therefore volume of frustum =
V=π * 20² * h/3 - π * 12² *h/3
The variables will cancel out each other
V = 20² - 12²
V = 400- 144
V = 256cm³
Therefore, the volume of the frustum(C) = 256cm³

The net pay is the amount left after taxes and deductions have been removed from the gross pay.
Her monthly gross pay is: $4111.93
The deductions are:
![\mathbf{FIT = \$102}](https://tex.z-dn.net/?f=%5Cmathbf%7BFIT%20%3D%20%5C%24102%7D)
![\mathbf{SIT = 3.2\%}](https://tex.z-dn.net/?f=%5Cmathbf%7BSIT%20%3D%203.2%5C%25%7D)
![\mathbf{CIT = 1.8\%}](https://tex.z-dn.net/?f=%5Cmathbf%7BCIT%20%3D%201.8%5C%25%7D)
Let her gross pay be x.
So, we have:
![\mathbf{Net = x - FIT - x \times SIT - x \times CIT}](https://tex.z-dn.net/?f=%5Cmathbf%7BNet%20%3D%20x%20-%20FIT%20-%20x%20%5Ctimes%20SIT%20-%20x%20%5Ctimes%20CIT%7D)
So, we have:
![\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}](https://tex.z-dn.net/?f=%5Cmathbf%7B3804.33%20%3D%20x%20-%20102%20-%20x%20%5Ctimes%203.2%5C%25-%20x%20%5Ctimes%201.8%5C%25%7D)
Express percentage as decimals
![\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}](https://tex.z-dn.net/?f=%5Cmathbf%7B3804.33%20%3D%20x%20-%20102%20-%20x%20%5Ctimes%200.032-%20x%20%5Ctimes%200.018%7D)
![\mathbf{3804.33 = x - 102 - 0.032x - 0.018x}](https://tex.z-dn.net/?f=%5Cmathbf%7B3804.33%20%3D%20x%20-%20102%20-%200.032x%20-%20%200.018x%7D)
Add 102 to both sides
![\mathbf{3906.33 = x - 0.032x - 0.018x}](https://tex.z-dn.net/?f=%5Cmathbf%7B3906.33%20%3D%20x%20-%200.032x%20-%20%200.018x%7D)
![\mathbf{3906.33 = 0.95x}](https://tex.z-dn.net/?f=%5Cmathbf%7B3906.33%20%3D%200.95x%7D)
Divide both sides by 0.95
![\mathbf{4111.93 = x}](https://tex.z-dn.net/?f=%5Cmathbf%7B4111.93%20%3D%20x%7D)
Rewrite as:
![\mathbf{x = 4111.93 }](https://tex.z-dn.net/?f=%5Cmathbf%7Bx%20%3D%204111.93%20%7D)
Hence, her monthly gross pay is: $4111.93
