put this solution on YOUR website!The volume of a sphere is given by:
but we have a hemisphere, which is half of a sphere, so the volume of a hemisphere would be given by:
We are given the diameter, so we need to divide by 2 to get the radius:
I used Excel, but you can use a calculator or do the arithmetic, either way, the answer comes out 0.4524 cubic meters
There are 1000 liters (or litres, if you prefer) in 1 cubic meter. So, rounded to the nearest liter, there are:

liters in the given hemisphere.
You can
put this solution on YOUR website!Find the volume of a hemisphere of diameter 1.2m to the nearest litres?
---------------
The volume of the sphere: V = (4/3)(pi)r^3
hemisphere = (1/2)V
radius = (1/2)diameter = (1/2)1.2m = 0.6 meter
-------------------------
Your Problem:
(1/2)V = (1/2)(4/3)(pi)(0.6)^3 = 0.452389... cubic meters
