Question

each sail on the windmill is 5 meters in length How much area do the sails cover as they turn from the force of the wind

Answer 1

78.5 meters

Explanation:

The formula for area is:
`\pi`*
`radius^(2)`

Now, let's plug in the equation:

3.14 *
`5^(2)`

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

Answer 2

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
