<span>Yes. I think that engineers may have to adapt their original plans during the construction of systems or products</span> because they might think that other people have good ideas to make it better or because exogenous variables may require that they adapt their original plans in order to successfully construct the system. <span />

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>
