A solid sphere of diameter 18cm is placed in an empty vertical cylindrical tank of diameter 24cm enough water is poured into the tank to cover the sphere if the sphere is then removed how far does the water fall

Answer 1

the volume of the sphere is 972π cm^3

since the area of the tank's cross-section is 144π cm^2, the height of the water column occupied by the sphere is

972π / 144π = 6.75 cm
