A cylindrical bucket with base 15 cm with water upto a height of 20 cm a heavy iron spherical ball of radius 9cm is drop into the bucket to submerge completely in the water. Find the incrrase in the level of water.
Answered by Reiny
volume of sphere = (4/3)πr^3
= (4/3)π(9^3)
= 972π cm^3

Increase in water volume = 972π

radius of cylinder = 7.5
so π(7.5)^2 h = 972π
56.25h = 972
h = 17.28 cm

So the water will rise 17.28 cm

check my arithmetic
