When the windmill turns, its sails will form a circle of 5m radius.
So area = pi*radius^2
= 3.14*5^2
= 3.14*25
= 78.5 sq.m
So area = pi*radius^2
= 3.14*5^2
= 3.14*25
= 78.5 sq.m
Answer:
78.5 meters
Step-by-step explanation:
The formula for area is: [tex]\pi[/tex]*[tex]radius^{2}[/tex]
Now, let's plug in the equation:
3.14 * [tex]5^{2}[/tex]
Simplify:
3.14 * 25
78.5m
Therefore, the wings cover 78.5 meters of area a they turn from the force of the wind.
Hope this helps! :D
