Answer:
7234.56.
Step-by-step explanation:
Given:
Diameter = 24 inches
To find:
Volume of beach ball = ?
Solution:
First of all find radius, r = half of diameter
r = ![\frac{24}{2} = 12 \ inches](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B2%7D%20%20%3D%2012%20%5C%20inches)
By using formula, ![Volume \ of \ sphere = \frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=Volume%20%5C%20of%20%5C%20sphere%20%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D)
![Volume\ of \ sphere = \frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=Volume%5C%20%20of%20%5C%20sphere%20%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D)
= ![\frac{4}{3} \times3.14\times12\times12\times12\\\frac{21703.68}{3} = 7234.56](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%5Ctimes3.14%5Ctimes12%5Ctimes12%5Ctimes12%5C%5C%5Cfrac%7B21703.68%7D%7B3%7D%20%20%3D%207234.56)
Therefore, the correct value of the volume, in cubic inches, of the beach ball is 7234.56.
You square root the whole equation.
