please help me. My answer was 1282.7 and it was incorrect.

Remember that the volume of a cone is:
[tex]V=\frac{1}{3}\pi r^2h[/tex]Using the formula and the data given, we'll get:
[tex]\begin{gathered} V=\frac{1}{3}\cdot(3.14)\cdot(7^2)\cdot(25) \\ \rightarrow V=1282.2 \end{gathered}[/tex]Thereby, the volume of the cone (rounded to the nearest tenth) is 1282.2 cubic feet.
