me ayudan porfa la necesito rapido!​

Answer 1

Respuesta:

       $640.73 dm^{2}$

Explicación paso a paso:

$Diametro: D = 34dm$

$Area-del-semiCirculo: A_{1} = \frac{\pi D^{2} }{8} =\frac{(3.14)(34)^{2} }{8} =\frac{3629.84}{8} =453.73dm^{2}$

$Altura: h = 11dm$

$Base: b = 34dm$

$Area-del-triangulo: A _{2} = \frac{b*h}{2} = \frac{34*11}{2} = \frac{374}{2} =187dm^{2}$

$Area-total: At = ?$

$At = A_{1} +A_{2} = 453.73dm^{2} +187dm^{2}$

$At = 640.73dm^{2}$
