Answer: ![249.48\ m^2; 369.168\ m^3](https://tex.z-dn.net/?f=249.48%5C%20m%5E2%3B%20369.168%5C%20m%5E3)
Step-by-step explanation:
Given
Cost of white-washing =Rs. 4989.60
Rate =20 per meter square
So, inside area of = ![\dfrac{4989.60}{20}=249.48\ m^2](https://tex.z-dn.net/?f=%5Cdfrac%7B4989.60%7D%7B20%7D%3D249.48%5C%20m%5E2)
The surface area of dome= ![4\pi\ r^2=249.48](https://tex.z-dn.net/?f=4%5Cpi%5C%20r%5E2%3D249.48)
![4\times 3.142\times r^2=249.48\\r^2=\frac{249.48}{4\times 3.142}=19.85\\r=4.455\ m](https://tex.z-dn.net/?f=4%5Ctimes%203.142%5Ctimes%20r%5E2%3D249.48%5C%5Cr%5E2%3D%5Cfrac%7B249.48%7D%7B4%5Ctimes%203.142%7D%3D19.85%5C%5Cr%3D4.455%5C%20m)
The volume of air in the dome ![V=\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
![V=\frac{4}{3}\cdot 3.142\cdot (4.45)^3\\V=369.17\ m^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Ccdot%203.142%5Ccdot%20%284.45%29%5E3%5C%5CV%3D369.17%5C%20m%5E3)
Doesn't ask what kind of cd's and what age it was aimed at
348 rocks because if you add 126 three times, or multiply it by 3, it equals 348. The numbers from the box you would use are 300, 30, and 18 then add them together
