Question

AYUDAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Answer 1

Respuesta:

          $2.8888 m^{2}$

Explicación paso a paso:

 Sin considerar dobleces de pestañas:

$Altura : h = 0.75 m$

$Radio : R = 0.4 m$

$\pi = 3.14$

Area total:

Fórmula:

$At = 2\pi Rh +2\pi R^{2}$

$At = 2\pi (0.4m)(0.75m)+2\pi (0.4m)^{2}$

$At = 2(3.14)(0.3m^{2} ) + 2(3.14)(0.16m^{2} ) = 1.884m^{2} +1.0048m^{2}$

$At = 2.8888 m^{2}$
