A spherical fish bowl is half-filled with water. The center of the bowl is C, and the length of segment AB is 20 inches, as shown below. Use Twenty two over seven for pi.

A sphere with diameter 20 inches is drawn.

Which of the following can be used to calculate the volume of water inside the fish bowl?

Yeah there it is, sorry forgot

can you take a screenshot of the choices. It's kind of hard to tell what the exponent and fractions are.

I think it's asking for half the volume of the sphere since it's half full of water. If the volume of the sphere is
$$V=\frac{ 4 }{ 3 }\pi r^3$$
Then half of that is 
$$V = \frac{ 2 }{ 3 }\pi r^3$$

oh ok I see, they don't want you to use pi.
so it looks like the 3rd one is correct
