Respuesta :

Given Information :

  • Radius of the turbine = 32 m
  • π = 3

To calculate :

  • Area covered by blade when the turbine makes 1 revolution.

Calculation :

We know that,

[tex]\bigstar \: \boxed{\sf {Area_{(Circle)} = \pi r^2}} \\ [/tex]

[tex] \sf \longmapsto {Area = \{3 \times (32)^2 \} \: m^2 } [/tex]

[tex] \sf \longmapsto {Area = \{3 \times 1024 \} \: m^2 } [/tex]

[tex] \longmapsto \sf \red {Area = 3072 \: m^2 } [/tex]

Therefore,

  • Correct option is option 4th.
