1. The user provided several expressions: $32\pi$, $64$, $64\pi$, and $16$. 2. We will analyze these numbers to find their relationships or simplify them. 3. Notice that $32\pi$ and $64\pi$ both involve $\pi$, so we can compare those separately. 4. $64$ and $16$ are constants and can be simplified or factored. 5. $64 = 16 \times 4$. This shows $64$ is four times $16$. 6. For the terms involving $\pi$, $64\pi = 2 \times 32\pi$. 7. Hence, $64\pi$ is twice $32\pi$. Final summary: - $64 = 4 \times 16$ - $64\pi = 2 \times 32\pi$ No explicit question was asked, but these are the relationships between the numbers provided.
