Find the amount of water displaced by a solid spherical ball of diameter 0.21 m.

`["Assume "pi=22/7]`

###### Advertisements

#### Solution

Radius (*r*) of ball = (0.21/2)m = 0.105 m

`"Volume of ball "=4/3pir^3`

`=[4/3xx22/7xx(0.105)^3]m^3`

= 0.004851 m^{3}

Therefore, the volume of the sphere is 0.004851 m^{3}.
