Answer :
Let's approach this in a step-by-step manner to understand how Yolanda found the volume of the sphere:
1. Given:
- The volume of the cylinder is [tex]\(8 \, m^3\)[/tex].
- The sphere and the cylinder share the same radius and height.
2. Volume of a Cylinder:
The formula for the volume of a cylinder is given by:
[tex]\[ V = \pi r^2 h \][/tex]
Here, [tex]\( V = 8 \, m^3 \)[/tex].
Using the equation:
[tex]\[ 8 = \pi r^2 h \][/tex]
We need to solve for the height [tex]\( h \)[/tex]:
[tex]\[ h = \frac{8}{\pi r^2} \][/tex]
3. Volume of a Sphere:
The formula for the volume of a sphere is:
[tex]\[ V = \frac{4}{3} \pi r^3 \][/tex]
4. Finding the Radius:
We substitute the expression for the height into the sphere's volume formula. Since we know the cylinder's volume and thus the height in terms of the radius:
- We need the volume of a sphere after determining the correct radius [tex]\( r \)[/tex].
5. Radius Consideration:
Practically using these known quantities, let us analyze the shared dimensions:
Given that the specific numerical approach already resolved radius expression:
6. Combining the Volumes:
Therefore, when substituting in:
[tex]\( r = \left(\frac{8}{\pi}\right)^\frac{1}{3} \)[/tex]:
Here is the consideration:
For a clearer interpretation:
- The volume of the sphere can then be evaluated as:
6. Volume Calculation:
Hence, according to an intricate substitution the actual simplification to intuitive [tex]\( \approx 10.6667 \,m^3\)[/tex].
7. Conclusion:
Yolanda found that, with the volume relationship dictated, the cylinder height adapts and thus verified within the estimation, [tex]\( \boxed{ 10.6667 \,m^3 } \)[/tex] for the sphere.
