Answer:
volume of the sphere is V=1766.25 
Step-by-step explanation:
step:1
<u>The volume of the sphere formula is V=
</u>
<u>step:2</u>
Given radius of the sphere r=7.5 ft
substitute given radius r=7.5 ft value in volume of the sphere formula
![V=[tex]\frac{4 pi r^{3} }{n}](https://tex.z-dn.net/?f=V%3D%5Btex%5D%5Cfrac%7B4%20pi%20r%5E%7B3%7D%20%20%7D%7Bn%7D)
\\
V=\frac{4(3.14)(7.5)^{3} }{3}[/tex]
V=1766.25
Final answer is V=1766.25
Answer: -11
Step-by-step explanation:
(n+8)* -4= 12
-8 -8
n* -4= 12
/-4 /-4
n= -11
I would say it equals 4 because if x=-4 than -x should equal 4 i may be wrong though
Answer:
31 aces
