This is the formula to determine the length of arc
length of arc = angle/360° × circumference
First we should find the circle circumference
c = 2 × π × r
c = 2 × 3.14 × 6
c = 37.68 miles
Second find the length of arc
length of arc = angle/360 × circumference
length of arc = 135/360 × 37.68
length of arc = 3/8 × 37.68
length of arc = (3 × 37.68)/8
length of arc = 113.04/8
length of arc = 14.13
The length of arc is 14.13 miles
126
A=(3*-1)-(2*0)= -3
B=(3*2)-(6*8)=-42
AB= (-3)*(-42)=126 :)

Answer:
$400
Step-by-step explanation:
Ok so they loose $200 per month.
10 students go for 1 hour per week and pay $15
10x15=150
$150 per week
4 weeks in the month
$150 x 4 = $600
-$200 rent
$600-$200=$400
They make $400 per month
