gavmur [86]

Answer:

$A_{big} = 1143.33cm^2$

Explanation:

The given parameters are:

$V_{small} = 1080$

$V_{big} = 1715$

$C_{small} = 840$

Required

Determine the curved surface area of the big cone

The volume of a cone is:

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

For the big cone:

$V_{big} = \frac{1}{3}\pi R^2H$

Where

R = radius of the big cone and H = height of the big cone

For the small cone:

$V_{small} = \frac{1}{3}\pi r^2h$

Where

r = radius of the small cone and H = height of the small cone

Because both cones are similar, then:

$\frac{H}{h} = \frac{R}{r}$

and

$\frac{V_{big}}{V_{small}} = \frac{\frac{1}{3}\pi R^2H}{\frac{1}{3}\pi r^2h}$

$\frac{V_{big}}{V_{small}} = \frac{R^2H}{r^2h}$

Substitute values for Vbig and Vsmall

$\frac{1715}{1080} = \frac{R^2H}{r^2h}$

Recall that: $\frac{H}{h} = \frac{R}{r}$

So, we have:

$\frac{1715}{1080} = \frac{R^2*R}{r^2*r}$

$\frac{1715}{1080} = \frac{R^3}{r^3}$

Take cube roots of both sides

$\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}$

Factorize

$\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}$

$\sqrt[3]{\frac{343}{216}} = \frac{R}{r}$

$\frac{7}{6} = \frac{R}{r}$

The curved surface area is calculated as:

$Area = \pi rl$

Where

$l = slant\ height$

For the big cone:

$A_{big} = \pi RL$

For the small cone

$A_{small} = \pi rl$

Because both cones are similar, then:

$\frac{L}{l} = \frac{R}{r}$

and

$\frac{A_{big}}{A_{small}} = \frac{\pi RL}{\pi rl}$

$\frac{A_{big}}{A_{small}} = \frac{RL}{rl}$

This gives:

$\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{L}{l}$

Recall that:

$\frac{L}{l} = \frac{R}{r}$

So, we have:

$\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{R}{r}$

$\frac{A_{big}}{A_{small}} = (\frac{R}{r})^2$

Make $A_{big}$ the subject

$A_{big} = (\frac{R}{r})^2 * A_{small}$

Substitute values for $\frac{R}{r}$ and $A_{small}$

$A_{big} = (\frac{7}{6})^2 * 840$

$A_{big} = \frac{49}{36} * 840$

$A_{big} = \frac{49* 840}{36}$

$A_{big} = 1143.33cm^2$

<em>Hence, the curved surface area of the big cone is 1143.33cm^2</em>

Is this code object-oriented, or is it procedural? what clues in the code itself did you use to determine what kind of code it i

Katen [24]

An Object-Oriented code or coding refers to a technique of programming that utilizes the identification of classes of objects that are closely tied to the functions with which they are related.

<h3>What is a Procedural Oriented Code?</h3>

This refers to a kind of programming language that utilizes a step-by-step method so as to break down a task into a set or a collection of factors or variables and routines or sub-routines using a set of instructions that are sequential.

Objects in programming refer to a type of abstract data that has a state and behavior. It is a specific instance of a class.

A class in programming is a templated definition of the techniques and variables of a certain type of object.

<h3>What are some of the principles and structures of coding?</h3>

There are 10 principles of coding. Some of them are:

Keep it simple
Separate concerns
Document your Code etc.

Some of these principles can be used in normal day-to-day activity and even in business. item 1 for instance can be used during communication. Effective communication is more effective when it is kept very simple.

It is to be noted that the code referenced in the question is unavailable hence the general answer.

What are the differences between a cursor, insertion point and mouse pointer?

Anna35 [415]

Answer:

Explanation:

A cursor is a pointer which indicates the position of the mouse on a computer's display monitor.

An insertion point is a location in a document where additional information is inserted when the user begins to type.

A mouse pointer is an image used to activate/control certain elements in a GUI (graphical user interface).

I know you asked for the differences, though i thought I'd add a similarity. All of these 3 things are similar, as they show where the position of the info/mouse is. :)

Hope this helps!
