Answer:
![\large\boxed{Surface\ Area=63\ cm^2}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BSurface%5C%20Area%3D63%5C%20cm%5E2%7D)
Step-by-step explanation:
We have
square with sides <em>s = 3cm</em>
four triangles with base <em>b = 3cm</em> and height <em>h = 9cm</em>.
The formula of an area of a square:
![A_\square=s^2](https://tex.z-dn.net/?f=A_%5Csquare%3Ds%5E2)
The formula of an area of a triangle:
![A_\triangle=\dfrac{bh}{2}](https://tex.z-dn.net/?f=A_%5Ctriangle%3D%5Cdfrac%7Bbh%7D%7B2%7D)
Substitute:
![A_\square=3^2=9\ cm^2\\\\A_\triangle=\dfrac{(3)(9)}{2}=\dfrac{27}{2}=13.5\ cm^2](https://tex.z-dn.net/?f=A_%5Csquare%3D3%5E2%3D9%5C%20cm%5E2%5C%5C%5C%5CA_%5Ctriangle%3D%5Cdfrac%7B%283%29%289%29%7D%7B2%7D%3D%5Cdfrac%7B27%7D%7B2%7D%3D13.5%5C%20cm%5E2)
The Surface Area:
![S.A.=A_\square+4A_\triangle\\\\S.A.=9+4(13.5)=9+54=63\ cm^2](https://tex.z-dn.net/?f=S.A.%3DA_%5Csquare%2B4A_%5Ctriangle%5C%5C%5C%5CS.A.%3D9%2B4%2813.5%29%3D9%2B54%3D63%5C%20cm%5E2)
Answer: Doubling the radius.
Step-by-step explanation:
The volume of a cone can be found with the following formula:
![V=\frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
Where "r" is the radius and "h" is the height of the cone.
Let's find the volume of the conical tent with a radius of 10.4 feet and a height of 8.4 feet.
Identifiying that:
![r=10.4\ ft\\\\h=8.4\ ft](https://tex.z-dn.net/?f=r%3D10.4%5C%20ft%5C%5C%5C%5Ch%3D8.4%5C%20ft)
You get this volume:
![V_1=\frac{1}{3}\pi (10.4\ ft)^2(8.4\ ft)\\\\V_1=951.43\ ft^3](https://tex.z-dn.net/?f=V_1%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%2810.4%5C%20ft%29%5E2%288.4%5C%20ft%29%5C%5C%5C%5CV_1%3D951.43%5C%20ft%5E3)
If you double the radius, the volume of the conical tent will be:
![V_2=\frac{1}{3}\pi (2*10.4\ ft)^2(8.4\ ft)\\\\V_2=3,805.70\ ft^3](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%282%2A10.4%5C%20ft%29%5E2%288.4%5C%20ft%29%5C%5C%5C%5CV_2%3D3%2C805.70%5C%20ft%5E3)
When you divide both volumes, you get:
![\frac{3,805.70\ ft^3}{951.43\ ft^3}=4](https://tex.z-dn.net/?f=%5Cfrac%7B3%2C805.70%5C%20ft%5E3%7D%7B951.43%5C%20ft%5E3%7D%3D4)
Therefore, doubling the radius will quadruple the volume of the tent.

Answer:
2.5 • 10^6
Explanation:
In order for 25 • 10^6 to be written in standard form, the ‘25’ needs to be less than 10. To do that we will move the decimal one place to the left so that 25 is now 2.5; it is now a number less than 10. It should now look like 2.5 • 10^6. It is now in standard form.
