Question

a sphere of diameter 12cm is dropped in a right circular cylindrical vessel partly filled with water. if the sphere is completelysubmerged in water the water level in the cylindrical vessel rises by [tex]38(5/9)cm find the diameter of the cylindrical vessel
?

Answer 1

Answer:

diameter=18 cm

Step-by-step explanation:

volume of sphere =volume of cylindrical part that rises the level of water

4/3pi. (12/2)^3=pi. (r)^2. (32/9)

4/3x6x6x6= (r)^2. (32/9)

8x36=(r)^2(32/9)

r=9

so diameter=18 cm
