    Volume of cone: 1/3 × b × h. b=base (area of circle on the bottom) and h=height of the cone. Can you do it now?

    Pretty sure it's not. What is the area you got for the base?

    I mean the base. Like the circle on the bottom. What was the area of the circle?

    The diameter of 10 is just a line, not the area of the circle. For reference, the area of a circle is \[A=πr ^{2}\] and the diameter/radius ratio is \[Diameter=2x (Radius)\]

    Just in case, the answer would be 150π, or (around) 471.238898038
