You are requiring opdatiog the variabile $a=167$ migt fots two dncimal places. Which of the raftowing is the right code to perform the action?

a$.a=$ tounita. $21$

b$.a-1$ ound $(2,+)$

c$.$ round $(a,2)$

d$.$ xound $(2,a)$

Convert the foltowing into Python expression

a$.=\sqrt[\phantom{2}]{3}+{}^2$

$q,$

b$.,$ area $=m{r}^2$

$q,$

c$.y=\frac{x^3+\sqrt[\phantom{2}]{y}}{\sqrt[\phantom{2}]{x^2+z^2}}$

$q,$

Write the output of the following programming expression. Given that $i=100$ and $j=$

a$.\{$:$pr{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}()++1\}=\{{\}}^{\text{'}\text{'}}.$format$(1,1,1+\frac{1}{2})q,$

b$.$ print $("\{2\}>\{1\}$ is $.$ format $($True$,1,j$

$q,$
