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,


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


\sf \longmapsto {Area = \{3 * (32)^2 \} \: m^2 }


\sf \longmapsto {Area = \{3 * 1024 \} \: m^2 }


\longmapsto \sf \red {Area = 3072 \: m^2 }

Therefore,

  • Correct option is option 4th.
