The volume of a sphere is 1/48 PI cubic meters. What is the length of the sphere’s radius? In your final answer, include all of your calculations. (ALL CALCULATIONS PLEASE )

Respuesta :

Volume of sphere = 4/3 πr^3
Volume = 1/48π
1/48 = 4/3 πr^3

0.02083 = 1.3 x 3.14 x r^3
r^3 = 0.02083/1.3 x 3.14
r^3 = 0.00693
r = 0.19 meters

Answer:

[tex]r=\frac{1}{4}\text{ m}=0.25\text{ m}[/tex]

Step-by-step explanation:

We have been given that volume of a sphere is [tex]\frac{1}{48}\pi\text{ m}^3[/tex]. We are asked to find the length of sphere's radius.

To find the radius of sphere we will use volume of sphere formula.

[tex]\text{Volume of sphere}=\frac{4}{3}\pi r^3[/tex], where r represents the radius of sphere.

Upon substituting our given volume in above formula we will get,

[tex]\frac{1}{48}\pi\text{ m}^3=\frac{4}{3}\pi r^3[/tex]

Let us multiply both sides of our equation by 3/4.

[tex]\frac{3}{4}\times\frac{1}{48}\pi\text{ m}^3=\frac{3}{4}\times\frac{4}{3}\pi r^3[/tex]

[tex]\frac{\pi}{4\times 16}\text{ m}^3=\pi r^3[/tex]

Dividing both sides of our equation by pi we will get,

[tex]\frac{\pi}{64\pi}\text{ m}^3=\frac{\pi r^3}{\pi}[/tex]

[tex]\frac{1}{64}\text{ m}^3=r^3[/tex]

Taking cube root of both sides of our equation we will get,

[tex]\sqrt[3]{\frac{1}{64}\text{ m}^3}=r[/tex]

[tex]\sqrt[3]{\frac{1}{4^3}\text{ m}^3}=r[/tex]

[tex]\frac{1}{4}\text{ m}=r[/tex]

[tex]r=\frac{1}{4}\text{ m}=0.25\text{ m}[/tex]

Therefore, the radius of sphere is 0.25 meters.
