Answer:
301.5936 cubic ft
Step-by-step explanation:
Formula for the volume of a cylinder is V = pi*r*r*h, where r represents the radius and h represents the height of the cylinder. Since radius is half the length of diameter, the pipe has a radius of 4/2 = 2 ft.
V = pi*r*r*h = 3.1416*2*2*24 = 301.5936 cubic ft
it would equal the same mixed number. 5 2/3
Answer: -72x+45y+72
Step-by-step explanation:
The Jasmine result is the good one because 1 mégas meter=1 000 000
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)
