To find the volume of a hemisphere, you can use the formula for the volume of a sphere and then divide by 2:
\[V = \frac { 2} { 3} \pi r^ 3\]
Given that the radius \(r\) is 5.9 meters, we can plug this value into the formula:
\[V = \frac { 2} { 3} \pi ( 5.9) ^ 3\]
First, calculate \(( 5.9) ^ 3\):
\[( 5.9) ^ 3 = 5.9 \times 5.9 \times 5.9 = 205.379\]
Now, multiply this result by \(\frac { 2} { 3} \pi \):
\[V = \frac { 2} { 3} \pi \times 205.379\]
Using \(\pi \approx 3.14159\):
\[V \approx \frac { 2} { 3} \times 3.14159 \times 205.379\]
First, calculate \(\frac { 2} { 3} \times 3.14159\):
\[\frac { 2} { 3} \times 3.14159 \approx 2.09439\]
Now, multiply by 205.379:
\[V \approx 2.09439 \times 205.379 \approx 430.1\]
So, the volume of the igloo is approximately \(\boxed{ 430.1} \) cubic meters.
Supplemental Knowledge
In geometry, calculating the volume of three-dimensional shapes is a fundamental concept. For a hemisphere, which is half of a sphere, the volume can be derived from the volume formula for a sphere.
Key Concepts:
1. Volume of a Sphere: The formula to calculate the volume of a sphere is \(V = \frac { 4} { 3} \pi r^ 3\), where \(r\) is the radius.
2. Volume of a Hemisphere: Since a hemisphere is half of a sphere, its volume is half that of the sphere:
\[V = \frac { 1} { 2} \left ( \frac { 4} { 3} \pi r^ 3 \right ) = \frac { 2} { 3} \pi r^ 3\]
3. Radius (r): The distance from the center to any point on the surface.
