Answer:
They used 3.14 for pi:
[tex]V=\frac{4}{3} \pi r^3[/tex]
[tex]V=\frac{4}{3} (3.14)(5)^3[/tex]
Step-by-step explanation:
[tex]V=\frac{4}{3}\pi r^3[/tex] is the volume of a sphere with radius r.
I think that is the diameter given in the picture.
The radius is half the diameter.
So the radius is 5 since the diameter is 10.
Plug in this gives you:
[tex]V=\frac{4}{3} \pi (5)^3[/tex]
