$1.\backslash (\backslash$mathbf$\{15\}\backslash )$ points

What would the following code display:

$```$

x$=8\mathrm{.}127$;

y$\}=25\mathrm{.}5317\backslash$mathrm$\{$ ;

z$=3\mathrm{.}14159$;

fprintf$(\text{'}$I have circle with radius $\%.\mathrm{.}2$f$.$

$\text{'},$ x$)$

fprintf$(\text{'}$I know I have to use the number $\%\%3\mathrm{.}2$f$,\text{'},$ z$)$

fprintf$(\text{'}$but I know the area is not f$.$lf$.$

$\text{'},$ x$+$z$)$

fprintf$(\text{'}$I think the area might be s$.\mathrm{.}3$f$.\text{'},$ y$)$

$```$
