A cylinder has volume 45 pie and radius 3. What is its height?
liraira [26]

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

A company has fixed monthly costs of $130,000 and production costs on its product of $32 per unit. The company sells its product
Svet_ta [14]

Answer:

The cost function is C(x)=32x+130000.

The revenue function is R(x)=66x.

The profit function is P(x)=34x-130000.

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

C(x)=(fixed \:cost)+x\cdot (variable \:cost)

If x units are sold and the price per unit is p(x), then the total revenue is

R(x)=x\cdot p(x)

and R(x) is called the revenue function.

If x units are sold, then the total profit is

P(x)=R(x)-C(x)

and P(x) 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 C(x)=32x+130000.

We know that the company sells its product for $66 per unit.

Therefore,

The revenue function is R(x)=66x.

The profit function is

P(x)=R(x)-C(x)\\P(x)=66x-(32x+130000)\\P(x)=34x-130000
