answer should be 2304 i think.
explanation: plug in your values, in this situation 3=pi, or the symbol you see to the right of the equal sign in the picture listed.
you now have v=3(8^2)(12)
(8^2 means 8 squared i don’t have the correct symbols)
now you can go ahead and solve by multiplying v=3(64)(12)
(64 is 8 squared or as listed above 8^2)
after multiplying you should get v=2304
sorry if this is incorrect, but i’m pretty sure it is right, hope this helps! :)
