Hello!
The formula for the volume of a sphere is shown below.
V=[tex] \frac{4}{3} \pi[/tex]r³
As we are given the radius we will plug it into the formula below. We will use 3.14 for pi.
V=[tex] \frac{4}{3} \pi [/tex](125)
V=[tex] \frac{4}{3}[/tex](392.5)
V=523.3333
We round to A) 523 in³.
I hope this helps!
