Determine the curved surface area of the big cone
The volume of a cone is:

For the big cone:

Where
R = radius of the big cone and H = height of the big cone
For the small cone:

Where
r = radius of the small cone and H = height of the small cone
Because both cones are similar, then:

and


Substitute values for Vbig and Vsmall

Recall that:
So, we have:


Take cube roots of both sides
![\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B1715%7D%7B1080%7D%7D%20%3D%20%5Cfrac%7BR%7D%7Br%7D)
Factorize
![\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B343%2A5%7D%7B216%2A5%7D%7D%20%3D%20%5Cfrac%7BR%7D%7Br%7D)
![\sqrt[3]{\frac{343}{216}} = \frac{R}{r}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B343%7D%7B216%7D%7D%20%3D%20%5Cfrac%7BR%7D%7Br%7D)

The curved surface area is calculated as:

Where

For the big cone:

For the small cone

Because both cones are similar, then:

and


This gives:

Recall that:

So, we have:


Make
the subject

Substitute values for
and 



<em>Hence, the curved surface area of the big cone is 1143.33cm^2</em>
Answer:
Bjarne Stroustrop published the first reference guide for C++
Explanation:
Bjarne Stroustrop is a computer scientist who created the C++ programming language while working at the AT&T Bell laboratory. He also published the first reference guide for the programming language.
In October 1985, the book, The C++ Programming Language, was published. It describes the c++ programming language and was the only documentation and reference guide for the programming language at the time. Newer editions have since been published.
Answer: They must be dated.
Explanation: If pyrotechnic VDSs are used, they must be dated. Expired VDSs may be carried on board, but a minimum of three unexpired VDSs must be carried in the vessel.
Answer:
When printing a single contact, go to File and then Print; the only style available is Memo style .
When printing multiple contacts, there are several styles to choose from
Explanation:
<em>The question has been answered (by you). I will help you with the explanation. The texts in bold in the answer section represent the answer.</em>
<em />
The question is an illustration of Microsoft outlook.
In Microsoft outlook, the default style of printing is the memo style of printing. This is the only form of printing allowed when printing single contacts. In other words, other forms of printing cannot be selected.
However, there are several options available when multiple contacts are to be printied. Some of the printing styles are: phone directory style, card style, medium booklet style, etc.
Gray isn't a color to be exact it a shade or what some people call it a shadow just like black but if you add more gray to a look lets say RED it will make it kinda faddy and more darker then it was
