    Answer:

    The radius of the cone is 14.99 units.

    Step-by-step explanation:

    We have,

    Volume of cone, V = 7300 cubic units

    Height of the cone, H = 31 units

    It is required to find the missing dimension. It means we need to find the radius of the cone say R.

    The volume of a cone is given by :

    V=\dfrac{1}{3}\pi R^2H

    R is radius

    R=\sqrt{\dfrac{3V}{\pi H}} \\\\R=\sqrt{\dfrac{3\times 7300}{3.14\times 31}} \\\\R=14.99\ \text{units}

    So, the radius of the cone is 14.99 units.
