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
For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.

Step-by-step explanation:
The area of a sector has the formula
Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:
and simplifying that a bit to look less threatening, but not by much:
and
Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.
