The volume of a cone is 16 cubic decimeters. If the height remains the same and the radius of the base is reduced to the original (1/3), what is the volume of the cone at this time?
一个圆锥的体积是16立方分米，如果高不变，底面半径缩小到原来的(1/3)，这时圆锥的体积是多少立方分米．

<output>1/3 = around 0.333333</output>

<gadget id="calculator">(1/3) ** 2</gadget>
<output>1/9 = around 0.111111</output>

<gadget id="calculator">16 * (1/9)</gadget>
<output>16/9 = around 1.777778</output>

<result>16/9 = around 1.777778</result>
