Answer: 58.11 cm³
Step-by-step explanation:
1. The volume can be calculated with the following formula:
![V=h*w*d](https://tex.z-dn.net/?f=V%3Dh%2Aw%2Ad)
Where <em>l</em> is the lenght, <em>w</em> is the width and <em>h</em> is the heigth of the smartphone.
2. You know that the dimensions are:
![h=4.9in\\w=2.3in\\d=8mm](https://tex.z-dn.net/?f=h%3D4.9in%5C%5Cw%3D2.3in%5C%5Cd%3D8mm)
3. Convert the height and the width from inches to centimeters, as following:
![h=\frac{4.9in*2.54cm}{1cm}=12.44cm](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B4.9in%2A2.54cm%7D%7B1cm%7D%3D12.44cm)
![w=\frac{2.3in*2.54cm}{1cm}=5.84cm](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2.3in%2A2.54cm%7D%7B1cm%7D%3D5.84cm)
4. Convert milimeters to centimeters:
![d=\frac{8mm}{10}=0.8cm](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B8mm%7D%7B10%7D%3D0.8cm)
4. Then, the volume is:
![V=(12.44cm)(5.84cm)(0.8cm)=58.11cm^{3}](https://tex.z-dn.net/?f=V%3D%2812.44cm%29%285.84cm%29%280.8cm%29%3D58.11cm%5E%7B3%7D)
Area of a trapezoid = h/2 ( a + b) where h = height and a and b are the lengths of the 2 parallel sides.
So here we have
Area = 12/2 ( 18 + 23)
= 246 in^2 Answer
ii . volume of a sphere = 4/3 pi r^3 so
1436.03 = 4/3 pi r^3
r^3 = 1436.03 / (4/3 * pi) = 342.827
r = cube root of 342.827 = 7.0 m Answer
