Question

24. Calcula el área sombreada:
20cm

Answer 1

Respuesta:

${d}^{2} = {20cm}^{2} + {20cm}^{2}$

${d}^{2} = 400 {cm}^{2} + 400 {cm}^{2}$

$d = \sqrt{800 {cm}^{2} }$

$d = 28.28cm$

$area \: cirulo - area \: cuadrdo$

$(20cm )^{2} - \pi(14.14 )^{2}$

$627.8cm ^{2} -400cm ^{2}$

$227.81cm ^{2}$
