1.25 is the slope 5/4 rise over run
S would be the annual sales of the electronic device. In this case, that number is in the millions.
Therefore, our 13.9 becomes 13.9 millions.
Or written out, it would be: 13,900,000
For this case we have that the cost of each pizza is given by the following function:
![S (r) = 0.1 \pi * r ^ 2](https://tex.z-dn.net/?f=S%20%28r%29%20%3D%200.1%20%5Cpi%20%2A%20r%20%5E%202)
Where:
r: It's the radius of the pizza
IF a pizza cost $26.32 we have:
![26.32 = 0.1 \pi * r ^ 2](https://tex.z-dn.net/?f=26.32%20%3D%200.1%20%5Cpi%20%2A%20r%20%5E%202)
We cleared the radius, using
:
![\frac {26.32} {0.1} = \pi * r ^ 2\\263.2 = 3.14r ^ 2\\\frac {263.2} {3.14} = r ^ 2\\83.82 = r ^ 2\\r = \pm \sqrt {83.82}](https://tex.z-dn.net/?f=%5Cfrac%20%7B26.32%7D%20%7B0.1%7D%20%3D%20%5Cpi%20%2A%20r%20%5E%202%5C%5C263.2%20%3D%203.14r%20%5E%202%5C%5C%5Cfrac%20%7B263.2%7D%20%7B3.14%7D%20%3D%20r%20%5E%202%5C%5C83.82%20%3D%20r%20%5E%202%5C%5Cr%20%3D%20%5Cpm%20%5Csqrt%20%7B83.82%7D)
We choose the positive value:
![r = 9.15](https://tex.z-dn.net/?f=r%20%3D%209.15)
So, the radius of the pizza is ![9.16 \ in](https://tex.z-dn.net/?f=9.16%20%5C%20in)
Then, the diameter is: ![2r = 2 * 9.15 = 18.30 \ in](https://tex.z-dn.net/?f=2r%20%3D%202%20%2A%209.15%20%3D%2018.30%20%5C%20in)
Finally, the diameter of the pizza is:![18.30 \ in](https://tex.z-dn.net/?f=18.30%20%5C%20in)
Answer:
Option B
<span>Cylinder Volume = </span><span>π <span>• r² • height
height = </span></span><span>Cylinder Volume / (PI * radius^2)

Answer:
XM = 7
Step-by-step explanation:
M is the midpoint of XY , thus
XM = MY ( given XY is 7 ) , then
XM = 7
