Question

calcule a area do hexagono cujo Raio mede 3M

Answer 1

$3 = \frac{l \sqrt{3} }{2}$
$l = 2 \sqrt{3}$
_________________•••_________________
$area \: = \frac{ 3 {l}^{2} \sqrt{3} }{2}$
$area = \frac{3 \times (2 \sqrt{3}) {}^{2} }{2}$
$area = \frac{3 \times 4 \times 3}{2}$
$area = 18 \:{m}^{2}$
