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.
