Find the amount of water displaced by a solid spherical ball of diameter 4.2 cm , when it is completely immersed in water. |
|
Answer» Given, diameter of a solid spherical ball = 42 cm `therefore` Radius of a solid spherical ball, `r =(42)/(2) = 2.1 cm` Now, volume of water displaced by a solid spherical ball when it is csompleley immersed in water= Volume of a solid spherical ball `= (4)/(3) pir^(3) = (4)/(3) xx (22)/(7) xx (2.1)^(3)` `= (4)/(3) xx (22)/(7) xx2.1 xx2.1 xx2.1` `=(814.968)/(21) = 38.808 = 38.81 cm^(3)` Hence, the volume of water displaced by a solid spherical ball, when it is |
