Answer:
Volume of the cone = 103.14 meter cube
Step-by-step explanation:
Height of the cone= 2.1 m
Diameter= 13.7 m
Radius= 13.7/2= 6.85 m
Volume of a cone :
![=\pi r^2\frac{h}{3}](https://tex.z-dn.net/?f=%3D%5Cpi%20r%5E2%5Cfrac%7Bh%7D%7B3%7D)
As, ![\pi =\frac{22}{7}=3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D%5Cfrac%7B22%7D%7B7%7D%3D3.14)
Putting the values in the formula:
Volume is :
![=3.14*(6.85*6.85)*\frac{2.1}{3} \\\\=3.14*(6.85*6.85)*0.7\\\\=3.14*46.92*0.7\\\\=3.14*32.85\\\\=103.14m^3](https://tex.z-dn.net/?f=%3D3.14%2A%286.85%2A6.85%29%2A%5Cfrac%7B2.1%7D%7B3%7D%20%5C%5C%5C%5C%3D3.14%2A%286.85%2A6.85%29%2A0.7%5C%5C%5C%5C%3D3.14%2A46.92%2A0.7%5C%5C%5C%5C%3D3.14%2A32.85%5C%5C%5C%5C%3D103.14m%5E3)
The volume of the cone is 103.14 meter cube
One laptop costs 32,750.
He bought 5 laptops.
So, 5 x 32,750 = 163,750.
Let d = cost of one desktop.
163,750 + d = 229,600.
Solve for d to find your answer.
