Hey there :)
We know the volume formula of a sphere is:
[tex] \frac{4}{3} [/tex][tex] \pi [/tex] (radius)³
We are given the radius = 16 in
And asked to use 3.14 for [tex] \pi [/tex]
Apply the formula
V = [tex] \frac{4}{3} (3.14)(16)^3[/tex]
= [tex] \frac{4}{3} (3.14)(4096)[/tex]
= 17,148.58667
≈ 17,148.59 in³
Your answer will be the first option
