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:


r=(1)/(4)\text{ m}=0.25\text{ m}

Explanation:

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

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


\text{Volume of sphere}=(4)/(3)\pi r^3, where r represents the radius of sphere.

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


(1)/(48)\pi\text{ m}^3=(4)/(3)\pi r^3

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


(3)/(4)*(1)/(48)\pi\text{ m}^3=(3)/(4)*(4)/(3)\pi r^3


(\pi)/(4* 16)\text{ m}^3=\pi r^3

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


(\pi)/(64\pi)\text{ m}^3=(\pi r^3)/(\pi)


(1)/(64)\text{ m}^3=r^3

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


\sqrt[3]{(1)/(64)\text{ m}^3}=r


\sqrt[3]{(1)/(4^3)\text{ m}^3}=r


(1)/(4)\text{ m}=r


r=(1)/(4)\text{ m}=0.25\text{ m}

Therefore, the radius of sphere is 0.25 meters.
