The volume of a pyramid with hight and base is 1/3 the volume of a rectangleular prisim with the same height and base
also the volume of a cone is 1/3 the volume of a cylinder with same height and base so just fun facts to know (helpful)
so volume of cylinder=1/3 times height tiimes pi times radius^2 subsitute use pi=3.14 height=12 radius=6 volume=1/3 times 12 times 3.14 times 6^2 volume=4 times 3.14 times 36 volume=452.16 cubic meters the naswer is the top left choice
Volume=pi*(radius^2)*(height of cone/3) so in this case Volume= pi*6^2*(12/3). Simplify pi*36*4. Simplify again and you get Volume=452.16 cubic meters.
