To simplify the expression \( \frac{3 r^{3}}{2 r} \), you can divide the numerator and the denominator by \( r \), which is a common factor. This gives you \( \frac{3 r^{2}}{2} \). So, your final simplified expression is \( \frac{3 r^{2}}{2} \). Now, if you want to evaluate \( \frac{3 r^{2}}{2} \) for a specific value of \( r \), just plug it in! For example, if \( r = 4 \), then you'd calculate \( \frac{3 \times 4^2}{2} = \frac{3 \times 16}{2} = \frac{48}{2} = 24 \). This expression is useful in applications such as calculating areas or volumes in geometry, so keep it handy!
