Answer:
[tex]A_{big} = 1143.33cm^2[/tex]
Explanation:
The given parameters are:
[tex]V_{small} = 1080[/tex]
[tex]V_{big} = 1715[/tex]
[tex]C_{small} = 840[/tex]
Required
Determine the curved surface area of the big cone
The volume of a cone is:
[tex]V = \frac{1}{3}\pi r^2h[/tex]
For the big cone:
[tex]V_{big} = \frac{1}{3}\pi R^2H[/tex]
Where
R = radius of the big cone and H = height of the big cone
For the small cone:
[tex]V_{small} = \frac{1}{3}\pi r^2h[/tex]
Where
r = radius of the small cone and H = height of the small cone
Because both cones are similar, then:
[tex]\frac{H}{h} = \frac{R}{r}[/tex]
and
[tex]\frac{V_{big}}{V_{small}} = \frac{\frac{1}{3}\pi R^2H}{\frac{1}{3}\pi r^2h}[/tex]
[tex]\frac{V_{big}}{V_{small}} = \frac{R^2H}{r^2h}[/tex]
Substitute values for Vbig and Vsmall
[tex]\frac{1715}{1080} = \frac{R^2H}{r^2h}[/tex]
Recall that:[tex]\frac{H}{h} = \frac{R}{r}[/tex]
So, we have:
[tex]\frac{1715}{1080} = \frac{R^2*R}{r^2*r}[/tex]
[tex]\frac{1715}{1080} = \frac{R^3}{r^3}[/tex]
Take cube roots of both sides
[tex]\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}[/tex]
Factorize
[tex]\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}[/tex]
[tex]\sqrt[3]{\frac{343}{216}} = \frac{R}{r}[/tex]
[tex]\frac{7}{6} = \frac{R}{r}[/tex]
The curved surface area is calculated as:
[tex]Area = \pi rl[/tex]
Where
[tex]l = slant\ height[/tex]
For the big cone:
[tex]A_{big} = \pi RL[/tex]
For the small cone
[tex]A_{small} = \pi rl[/tex]
Because both cones are similar, then:
[tex]\frac{L}{l} = \frac{R}{r}[/tex]
and
[tex]\frac{A_{big}}{A_{small}} = \frac{\pi RL}{\pi rl}[/tex]
[tex]\frac{A_{big}}{A_{small}} = \frac{RL}{rl}[/tex]
This gives:
[tex]\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{L}{l}[/tex]
Recall that:
[tex]\frac{L}{l} = \frac{R}{r}[/tex]
So, we have:
[tex]\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{R}{r}[/tex]
[tex]\frac{A_{big}}{A_{small}} = (\frac{R}{r})^2[/tex]
Make [tex]A_{big}[/tex] the subject
[tex]A_{big} = (\frac{R}{r})^2 * A_{small}[/tex]
Substitute values for [tex]\frac{R}{r}[/tex] and [tex]A_{small}[/tex]
[tex]A_{big} = (\frac{7}{6})^2 * 840[/tex]
[tex]A_{big} = \frac{49}{36} * 840[/tex]
[tex]A_{big} = \frac{49* 840}{36}[/tex]
[tex]A_{big} = 1143.33cm^2[/tex]
Hence, the curved surface area of the big cone is 1143.33cm^2

Create a while loop to try making a video game turn based battle.
Then have a monster health value and a player health value.
The player can then choose to attack, heal, or do magic.
If they choose to attack, roll one die and take that damage away from the monsters health.
If they choose to heal then add a dice roll to the player's hp.
If they choose magic then take two dice rolls away from the enemy.

Major innovation made from establishment of abacus to the development of fifth dev of computer generation
Explanation:
The establishment of the Abacus brought about one of the first counting device (calculator). This device was a mechanized computer that supported numeric calculations. However, the process was entirely manual and mechanized. This innovation led to;
First-generation of computers, although not entirely manually operated like Abacus, made use of vacuum tubes, were very big in size and could store only a small amount of information.
Second Generation of computers unlike the first generation that uses vacuum tubes, this one came with new technology; the use of transistors. The computers were smaller in size than vacuum tubes.
Third Generation computers made use of IC (Integrated circuits) for the first time. Contained higher storage capacity and was more reliable than previous generations.
Fourth Generation computers became known as the personal computer generation. This generation brought the use of personal computers on a personal level as they use microprocessors, was easy to carry about, had larger storage capacity and faster speed of operations.
Fifth-generation of computers is known as the age of artificial intelligence. These computers were programmed with the ability to make decisions just like a human being would.
