Answer:
5 units
Step-by-step explanation:
The <u>volume of the cylinder</u> is the area of the circle multiplied by it's height. Therefore, the volume of the cylinder is πr² × h, which when simplified, gives us πr²h. Let's substitute the volume and the radius in the formula to find the height.
⇒ πr²h = Volume of cylinder
⇒ (π)(3²)(h) = 45π
Now, simplify the equation to evaluate the area of the cylinder.
⇒ (π)(3²)(h)/(3²)(π) = 45π/(3²)(π)
⇒ (h) = 45π/(9)(π) = 45/(9) = 5 units
$495-15%=$420.75
$420.75+8%=$454.41

Answer:
The cost function is
.
The revenue function is
.
The profit function is
.
Step-by-step explanation:
We have the following definitions:
The cost function is a mathematical formula that gives the total cost to produce a certain number of units. It consists of variable costs and fixed costs and is given by

If
units are sold and the price per unit is
, then the total revenue is

and
is called the revenue function.
If
units are sold, then the total profit is

and
is called the profit function.
Applying the above definitions we get that:
We know that the company has fixed monthly costs of $130,000 and production costs on its product of $32 per unit.
Therefore,
The cost function is
.
We know that the company sells its product for $66 per unit.
Therefore,
The revenue function is
.
The profit function is
