In the figure, a cylindrical container of base radius 3cm is filled with 59.4cm*(3) of water. When a stone is put in the water, the rise in water level is 1.4cm. Find a) the volume of the stone b) the depth of water 請用中文解釋一下,謝謝
最佳解答:
(a) The volume of stone equals to the volume of water rise Hence, volume of stone = 1.4 x (pi x 3^2) cm^3 = 39.58 cm^3 [ pi = 3.14159...] (b) Height of water before stone is put in = 59.4/(pi x 3^2) cm = 2.1 cm Hence, depth of water = (2.1 + 1.4) cm = 3.5 cm
