A is the name of a that is half of a .
Therefore, the of a hemisphere with
r is half the with radius
r.
Volume of a HemisphereV=21(34πr3)⇔V=32πr3
To use this we first need to calculate the radius. To do so, we will consider the given hemisphere.
In the diagram we can see that the radius is
1.4 meters. We can substitute this value for
r in the formula for the volume of a hemisphere and evaluate.
V=32πr3
V=32π(1.4)3
V=32π(2.744)
V=32(2.744)π
V=32(2.744)π
V=35.488π
V=5.747020…
V≈5.7
The volume of the hemisphere, to the nearest tenth, is
5.7 cubic meters.
