Find the diameter of a cone that has a volume of 104.67 cubic inches and a height of 4 inches. Use 3.14 for pi.
Lady bird [3.3K]

Answer:

Step-by-step explanation:

The volume of a cone is

V=\frac{1}{3}\pi r^2h

Filling in what we have:

104.67=\frac{1}{3}(3.14)r^2(4)  and simplifying a bit:

104.67=\frac{1}{3}(12.56)r^2

Multiply both sides by 3 to get:

314.01=12.56r^2

Divide both sides by 12.56 to get:

25.00079618=r^2 and take the square root of both sides to find the radius:

r = 5

If the radius is 5 and the radius by definition is half the diameter, then the diameter is 10 inches.

Help!! <br><br> I think I got these wrong, so please help!! Thank you!
Andrew [12]

Answer:

(x+3)(x+4)(x-4)

x+2 and x-3 are not factors but x-4 is

Step-by-step explanation:

let's factor it :)

x^3 + 3x^2 - 16x -48

first we will factor this:

x^3 + 3x^2

x^2(x + 3)

then factor the second part :

- 16x - 48

-16(x + 3)

so now,

x^2(x + 3) - 16(x + 3)

factor out x+3

(x+3)(x^2 - 16)

factor x^2 - 16

(x+3)(x+4)(x-4)

Assume that the short-run cost and demand data given in the tables below confront a monopolistic competitor selling a given prod
Damm [24]

Given the information stated above, the firms maximum total profit will be $90. (Option A) See the explanation below.

<h3>What is Maximum Total Profit?</h3>

Maximum total profit is the highest profit

<h3>What is the calculation supporting the above answer?</h3>

It is to be noted that the attached excel spread sheet was computed using the following formulas:

MC(n) = TC(n) - TC(n-1)

MC(n) = marginal cost of nth unit

TC(n) = Total cost of n units of output

MC(1) = 40-25=15 and so on

Recall that

Total Revenue (TR) = Price * Quantity

that is:

TR = P * Q

Marginal Revenue of the nth unit of output  =

TR of the n unit of output - TR of the n-1 units of output.

MR(n)=TR(n)-TR(n-1)

MR(1)=55-0=55 and so on

Recall that Profit = TR  - TC

Thus,

Profit (0) = 0 - 25

= -25 and so on

By observation on the sheet, the maximum profit (that is highest profit attainable) is given as $90.

This corresponds with

  • the Quantity of 4 Unit
  • The Marginal Revenue of 25; and
  • Marginal Cost of 15.

Hence, option A is correct.
