Kaepernicks

can you provide a example?

I would say it's about $${\mathtt{2.986\: \!431\: \!478\: \!97}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{1}}}$$

It would be $12.

Found on the calculator on the main 

It's about:

 $${{\mathtt{3}}}^{-{\mathtt{1.9}}} = \left({\frac{{\mathtt{1}}}{{{\mathtt{3}}}^{{\mathtt{1.9}}}}}\right) = {\mathtt{0.124\: \!013\: \!686}}$$

For volume:

 $${\mathtt{V}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{h}}$$

For surface area:

$${\mathtt{A}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{r}}{\mathtt{\,\times\,}}{\mathtt{h}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}$$

For lateral surface:

$${\mathtt{L}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{r}}{\mathtt{\,\times\,}}{\mathtt{h}}$$

1) don't ask on a math forum.

2) that's it

$${\frac{{\mathtt{1}}}{{\mathtt{5}}}} = {\mathtt{0.2}}$$

Simply divide 1 by 5, then multiply by 100

$${\mathtt{0.2}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\mathtt{20}}\%$$

Makes more sense now...I wasn't sure what "16 from" meant
