area:
$a = \pi {r}^{2}$
$a = 3.14 \times {10}^{2} = 314$

circumference:
$c = \pi \times diameter$
$c = 3.14 \times 20 = 62.8$

Simply by using rationalize denominators.<br><br> 2a^-1/2

Advocard [28]

Pemdas, so exponent before multiply
so do a^-1/2 then multiply it by 2

remember that $x^ \frac{m}{n}= \sqrt[n]{x^m}$ and
$x^{-m}= \frac{1}{x^m}$
therefor, $a^ \frac{-1}{2}= \frac{1}{a^ \frac{1}{2} } = \frac{1}{ \sqrt{a} }$
the we multiply by 2

$\frac{2}{ \sqrt{a} }$
