Question 531190: A hemisphere of 15 cm internal radius is filled with water to the brim. How many liters of water does it hold? Answer by lmeeks54(111) (Show Source):
You can put this solution on YOUR website! A hemisphere is 1/2 a sphere.
The formula for the volume of a sphere is 4/3 pi r^3
The conversion between cubic cm and liters is 1 cm = .001 liters
...
Given: r = 15 cm
...
Calculate the volume of the sphere:
4/3 (pi) (15^3)
~14,137 cu cm
...
convert to liters:
14,137 cu cm * .001 liters/cu cm
~14.14 liters
...
Divide by 2 to derive the volume of the hemisphere:
~14.14/2
...
~7.07 liters is the answer to the question
