TO find the volume of a sphere the formula is 4/3*PI(22/7)*r^3

Yes, but is point C ON segment AB? If it isn't we have to approach it completely differently.

Alright. Last question.
And you're trying to find the volume of the water or the bowl?

Alright. The formula for the volume of a sphere is:
\[V = \frac43πr^{3}\]
Now, the formula for the volume of half the bowl which is the water is half o fhte formula.
\[V = \frac46πr^{3}\]
\[V = \frac46π(12)^{3}\]
Can you solve from here?
