A cylinder of radius of 10cm.
It already contains water to depth of 15cm.
A metal sphere with volume 900cm^3 is placed in the water.
Calculate the height that the water level rises
:
Find the vol of water in the cylinder
V =
V =
V = 4712.4 cu/cm of water
:
Find the total volume of the water and the sphere
4712.4 + 900 = 5612.4 cu/cm
:
Find the height (h) of the water when displaced by the sphere
= 5612.4
h =
h = 17.8647 cm is the height
:
;
Check this by finding the vol of the water between 17.8647 - 15 = 2.8647cm
V =
V = 899.97 ~ 900, the vol of the sphere
