Answer:
![V=229612.5\ cm^3](https://tex.z-dn.net/?f=V%3D229612.5%5C%20cm%5E3)
Step-by-step explanation:
Given that,
The height of a cylinder, h = 325 cm
Diameter, d = 30 cm
Radius, r = 15 cm
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
![V=\pi r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h)
Putting all the values,
![V=3.14\times (15)^2\times 325\\\\V=229612.5\ cm^3](https://tex.z-dn.net/?f=V%3D3.14%5Ctimes%20%2815%29%5E2%5Ctimes%20325%5C%5C%5C%5CV%3D229612.5%5C%20cm%5E3)
So, the volume of the cylinder is
.
20% of $720( original cost)= $144 (discount)
$720- $ 144 = $576 (discounted cost)
5% tax = $36 (tax payed)
tax + cost of phone = $612 (total of both tax and discounted cost)
20% of $612=$122.40 (deposit cost?)
The area of his garden used for for growing roses is 144m^2
BE = 6cm
BD = 12 cm
For a square, the diagonal are equal
so :::
AC = BD = 12 cm
Done :)
