Answer:
Volume of sphere is ![35.98cm^3](https://tex.z-dn.net/?f=35.98cm%5E3)
Step-by-step explanation:
It is given that Hal says that volume of sphere is ![36cm^3](https://tex.z-dn.net/?f=36cm%5E3)
Volume of sphere is given by ![V=\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
![\frac{4}{3}\pi r^3=36](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%3D36)
![\pi r^3=27](https://tex.z-dn.net/?f=%5Cpi%20r%5E3%3D27)
![r^3=8.594](https://tex.z-dn.net/?f=r%5E3%3D8.594)
![r=2.048cm](https://tex.z-dn.net/?f=r%3D2.048cm)
Now using 3.14 in place of ![\pi](https://tex.z-dn.net/?f=%5Cpi)
Now volume of sphere is
![V=\frac{4}{3}\times 3.14\times 2.048^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Ctimes%203.14%5Ctimes%202.048%5E3)
![V=35.98cm^3](https://tex.z-dn.net/?f=V%3D35.98cm%5E3)
Therefore volume of sphere when we use 3.14 in place of
is ![35.98cm^3](https://tex.z-dn.net/?f=35.98cm%5E3)
And the Hal likely error is he uses
directly for calculation of volume.
The answer is $6.43. Hope this helps
Prime x² + 25 is prime (unfactorable).
Here's what the other options come out to:
(x + 5)(x + 5) = x² + 10x + 25
(x + 5)(x − 5) = x² − 25
(x − 5)(x − 5) = x² − 10x + 25
If you are trying to find where he is the answer is -29.7
Hope this helps!
