Answer: 58.11 cm³
Step-by-step explanation:
1. The volume can be calculated with the following formula:

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:

3. Convert the height and the width from inches to centimeters, as following:


4. Convert milimeters to centimeters:

4. Then, the volume is:

Hi there!
Since the slope of a line perpendicular to a line is always the negative inverse of that slope, you just switch the numerator and denominator around and add or omit the negative sign to the original slope.
The answer would be -2.
Hope this helps!

The polynomial p(x) can be found by multiplying 'x-3' to every term

Now distribute and you have your answer.
Vcylinder-Vsphere=water
Vcylinder=hpir^2
Vsphere=(4/3)pir^3
given
cylinderradius=30 and h=100
Vcylinder=100pi30^2=100pi900=90000pi
let's leave it in terms of pi for more exactness
sphereradius=12
Vsphere=(4/3)pi12^3=2304pi
cylinder-sphere=90000pi-2304pi=87696pi
using pi=3.14
water=275365.44 cubic cm
last option is corrrect
