Question
A cylindrical can whose diameter is 24 cm filled up with
sufficient quantity of coldrink, a solid spherical ball of radius 6 cm is completely immersed in it. Then the increase in height of coldrink is?Solution
Volume of Cylinder. π(12)²h = π(12)²×12 - 4/3 π(6)³ h ⇒ 12 - 2 = 10 Change in height = (12 - 10) = 2 cm.
