<span>The volume V of a sphere is four-thirds times pi times the radius cubed.
V=4/3*Pi*Radius^3
Hence the answer is D) 33,493.3 cm^3
V = 4/3 * Pi * 20^3 = 33,493.3 cm^3</span>
Answer:
∅ = 50°
Step-by-step explanation:
YOU NEED A CALCULATOR TO SOLVE THIS!
You need to use Law of Sines
![\frac{a}{sinA} =\frac{b}{sinB} = \frac{c}{sinC}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7BsinA%7D%20%3D%5Cfrac%7Bb%7D%7BsinB%7D%20%3D%20%5Cfrac%7Bc%7D%7BsinC%7D)
Here you will be doing ![\frac{a}{sinA} =\frac{c}{sinC}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7BsinA%7D%20%3D%5Cfrac%7Bc%7D%7BsinC%7D)
a and c are the lengths, while A and C are the angles
you want to get the denominators out from underneath so multiply both sides by sinA and sin43
![3.46sin43 = 2.54sinA](https://tex.z-dn.net/?f=3.46sin43%20%3D%202.54sinA)
Now you want to get sinA alone so divide both sides by 2.54
now get A alone
put that into the calculator
![49.61741033 = A](https://tex.z-dn.net/?f=49.61741033%20%3D%20A)

Answer:
![2x^{2} +20x+53](https://tex.z-dn.net/?f=2x%5E%7B2%7D%20%2B20x%2B53)
Step-by-step explanation:
2(x^2 + 10x + 25) + 3
2x^2 + 20x + 50 + 3
2x^2 + 20x + 53
