(1)测量记录圆柱形容器的底面直径是10厘米;
(2)把铅锤放入容器中,直到把铅锤浸没,测量记录此时水面高度为14厘米;
(3)取出容器中的铅锤,测量记录此时水面高度10厘米;
请你根据实验数据算一算这个圆锥形铅锤的体积。如果这个铅锤的高是6厘米,那么它的底面积是多少平方厘米?

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
