\(\displaystyle{S}{A}={2}\pi{r}{\left({h}+{r}\right)}\)
Substitute
\(\displaystyle{S}{A}={2}\pi{\left({3}\right)}{\left({4}+{3}\right)}\)
\(\displaystyle={42}\pi{c}{m}^{{2}}\)
\(\displaystyle\approx{131},{94}{c}{m}^{{2}}\)

Consider two independent distributions that are mound-shaped. A random sample of size \(n_{1}=36\) from the first distribution showed \(x_{1}=15\), and a random sample of size \(n_{2}=40\) from the second distribution showed \(x_{2}=14\). Based on the confidence intervals you computed, can you be 95% confident that \(\mu_{1}\) is larger than \(\mu_{2}\)? Explain.
