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,

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

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

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

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

Therefore,

• Correct option is option 4th.
