Find thy radius.

Thy radius is 7.25 (D / 2 = R)

Thy formula for area is A = (pi)r^2

Substitute and Solve

A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625

Therefore, the area is about 165.

this will put her working to 10 hrs a day and subtracting 1 hr break, the total working period would be 9 hrs a day.

And, total working hours per week would be (9*5) hrs = 45 hrs

thus, her total salary per week would be $(45*16.12) = $725.40
