In the experiment class, obviously put a conical lead cone into a cylindrical container with a bottom area of 25 decimeters and a water surface height of 3 decimeters. The water surface rises by 0.6 decimeters. It is known that the plumb weight is 2 decimeters high. Find the lead What is the area of the hammer's base?
实验课上，明明把一个圆锥形铅锥放入底面积是25平方分米，水面高3分米的圆柱形容器中，水面上升了0.6分米，已知铅锤高2分米，求铅锤的底面积是多少平方分米？
<gadget id="calculator">3.14 * 25 * 0.6</gadget>
<output>47.1</output>

<gadget id="calculator">3 / 2</gadget>
<output>3/2 = around 1.5</output>

<gadget id="calculator">47.1 * (3/2)</gadget>
<output>70.65</output>

<result>70.65</result>
