Question

Can someone please help me with this is area of circles

Answer 1

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.
