It is known that the height of a cone is equal to that of a cylinder, and the volume of the cone is (1/2) the volume of the cylinder, then the area of the base of the cone is the area of the base of the cylinder
已知一个圆锥与一个圆柱的高相等，且圆锥体积是圆柱体积的(1/2)，那么圆锥底面积是圆柱底面积的多少
<gadget id="calculator">1 / 2</gadget>
<output>1/2 = around 0.5</output>

<gadget id="calculator">3 * (1/2)</gadget>
<output>3/2 = around 1.5</output>

<result>3/2 = around 1.5</result>
