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

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
