Answer:
V = 15.7*x^2 + 125.6*x + 251.2 I'd use this as an answer, but it depends how you have been told to treat pi. This answer is also possible.
V = 5*pi*x^2 + 40*pi*x + 80*pi
I can't really tell you which one to use.
Step-by-step explanation:
Givens
V=pi*r^2 * h
pi = 3.14
r = (x + 4)
h = 5
Solution
V = pi * (x + 4)^2 * 5
V = pi * (x^2 + 8x + 16)*5
V = pi * (5x^2 + 40x + 80) Now the question is what to do with pi.
V = 5*pi*x^2 + 40*pi*x + 80*pi
That one possible answer. The other is to give pi a value
V = 15.7*x^2 + 125.6*x + 251.2
C.2x+2+3x because you have 2x’s a 2 and 3 w’s
Ronald’s monthly income = $100,482/12 = $8373.50
Don’t know what the second question is asking
Answer: 5 milimeters.
Step-by-step explanation:
The formula for calculate the volume of a rectangular prism is:
![V=lwh](https://tex.z-dn.net/?f=V%3Dlwh)
Where "V" is the volume, "l" is the lenght, "w" is the width and "h" is the height.
You know that the volume, the lenght, and the width of this rectangular prism are:
![V=750mm^3\\l=15mm\\w=10mm](https://tex.z-dn.net/?f=V%3D750mm%5E3%5C%5Cl%3D15mm%5C%5Cw%3D10mm)
Substitutute these values into the formula and solve for the the height "h":
![750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm](https://tex.z-dn.net/?f=750mm%5E3%3D%2815mm%29%2810mm%29h%5C%5C%5C%5Ch%3D%5Cfrac%7B750mm%7D%7B%2815mm%29%2810mm%29%7D%5C%5C%5C%5Ch%3D5mm)
