Pls help meeee I don’t understand this at alll

Answer:
you need the formula for the cone , Korc
Step-by-step explanation:
formula for cone = [tex]\frac{1}{3}[/tex]*π*[tex]r^{2}[/tex]*h
they tell us that the diameter is 8 so r = 4
and that h = 9
volume of cone = [tex]\frac{1}{3}[/tex]*π*[tex]4^{2}[/tex]*9
VoC = 150.796
VoC = 150.8 ( to the nearest 10th)
