Hey!

So, it looks like we got the volume of a sphere. We know that the formula for it when we got the diameter is, [tex]V=\frac{\pi d^3}{6}[/tex]
We are going to use 3.14 for [tex] \pi [/tex]
[tex]V=\frac{3.14* d^3}{6}[/tex]
Let's plug in the values,
[tex]V=\frac{3.14*10^3}{6}[/tex]
Simplify,
[tex]V=\frac{500*3.14 }{3}[/tex]
Our volume of the beach ball is,
V ≈ 523.333333333
Round to the nearest tenth. 
V 
≈ 523.3 in³

Thanks!
