    Answer:

    343π

    Step-by-step explanation:

    To find the volume of a cone, we have to use this formula

    \frac{1}{3} × π × r² × h

    Where ‘r’ is the radius and ‘h’ is the height

    Let’s start putting in the value’s

    We have diameter but in the formula we need the radius so we half the diameter to get the radius so 14 ÷ 2 = 7

    \frac{1}{3} × π × r² × h

    \frac{1}{3} × π × 7² × 21

    →  Simplify the expression

    \frac{1}{3}  × π × 49 × 21

    → Simplify it further

    343π
