S = 6 Pi cm
S ≈ 18.8 cm


7) S = 9 ft * 7 Pi / 4

Alex_Xolod [135]

Answer:

Gross pay per days is 5h+8 dollars

we are given

total gross pay =35h+56 dollars

total number of days =7

we know that

gross pay per day = ( total gross pay)/(total number of days)

we can plug values

gross pay per day is

=\frac{35h+56}{7}

we can simplify it

=\frac{7(5h+8)}{7}

=5h+8
