Step-by-step explanation:
we know that
The circumference of a circle is equal to

In this problem we have a 3/4 of a circle
so
the circumference is equal to


we have

substitute


Let the number of pants have to be made be x.
So,
9.55 * x = 525.00
x =

≈ 54.97
Thus, the number of pants have to be made are 54.
their is no answer
to that problem
-2y-4=4y-4
2) cancel 4 out on both sides
-2y=4y
3) divide both sides by -2
y=-2y
4) subtract both sides by -2y
y+2y=0
5)3y=0
6) divide by 3
Y=0
