By definition, the volume of a cone is given by: v = (pi * r ^ 2 * h) / 3 Where, r: radius h: height Clearing the radio we have: r = root ((3 * v) / (pi * h)) Substituting values: r = root ((3 * (256)) / (3.14 * (16))) r = 3.91 cm Answer: The radius of the cone is: r = 3.91 cm Note: a response option is missing
