The area of the sector =28.26feet^2

Step-by-step explanation:

The area of the sector= $\frac{\beta }{360}*\pi *r^2$

Given:

$\beta =90\\r=6feet$

Putting the values in the formula:

Area of the sector:

$=\frac{90}{360}*3.14*6*6$

$=\frac{90}{360} *3.14*36$

$=\frac{1}{4}*3.14*36$

=3.14*9

=28.26feet^2

The area of the sector =28.26feet^2

3450 workers in total

Step-by-step explanation:

since 60% is men the 40% are the 1380 women

1 way:

divide 40 and 1380 by 4 to find how many workers in 10%

- 40/4=10 1380/4=345 -> 10% are 345 workers

10%*10=100% 345*10=3450 workers in total

second way:

40%/2 = 20% 1380/2=690

100/20=5 690*5=3450
