Answer:
900 ft cubed
Step-by-step explanation:
v=pi*r sqaured* h
The radius is 5 and sqaure 5 to get to 25. Multiply that by pi, which in your case is 3, and you get 25. Then mulitply that by 12, height, and you get your answer is 900.
Lmk if you need more help
Also, to do this on the calulator is easy as well. Just times pi(3 for you) by the raduis twice and then times that by the height. For example, for this question, I just typed in my calculator, 3 times 5 times 5 times 12 and I got 900.
Sorry if this doesn't make sense lol I'm not good at explaining things.
