How do you find the diameter of a sphere if you have the volume. Will give Brainliest
Answers
Answer:
Diameter of a sphere formula is d=2 * r
Step-by-step explanation:
Answer:
d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2) (see below for explanation)
If volume = 34, d ≈ 4
Step-by-step explanation:
The volume of a sphere is:
V = (4/3) · π · r³
To find the diameter, you need to find the radius first. Isolate it to one side:
[tex]\frac{V}{(4/3)(pi)}[/tex] = r³
r³ = [tex]\frac{V}{(4/3)(pi)}[/tex]
∛r³ = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
So you would first multiply 4/3 by pi, then divide volume by that. Then cube root the whole thing. This will get you the radius.
Double this. This will get you the diameter.
r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2)
If the volume is 34, then:
d = {∛ [tex]\frac{34}{(4/3)(pi)}[/tex]} x (2)
4/3 (pi) = 4.188...
34/41.88... = 8.116...
∛8.116... = 2.009...
2.009...(2) = 4.019...
d = 4.019389542
d ≈ 4
look at the image and answer the question.
Answers
Answer:
So solution: [tex]6(x=2)+2(y=1)=14[/tex] and [tex]5(x=2)-2(y=1)=8[/tex]
([tex]x[/tex])=2
([tex]y[/tex])=1
Step-by-step explanation:
Because, 6[tex]x=2[/tex] + 2[tex]y=1[/tex] = 14 | 6 * 2 = 12 | 2 * 1 = 2 | 12 + 2 = 14 |
Because 5[tex]x=2[/tex] - 2[tex]y=1[/tex] = 8 | 5 * 2 = 10 | 2 * 1 = 2 | 10 - 2 = 8 |
So that's why the answer is ([tex]x[/tex])=2, and ([tex]y[/tex])=1
