1 answer:

4 0

45° is exactly 1/8 of a full circle (45/360 = 1/8) 
So the length of the arc would be 1/8 of a full circumference:
C = 2π r
C = 2π(8)
C = 16π

Take 1/8 of this:
1/8C = (1/8)16π = 2π

Answer:
Exact answer --> 2π inches
(Approx. answer --> 6.28 inches)

Maru [420]

1) How many weeks will Jake and Seth be equal? set the equations equal to each other and solve for x:

5x + 85 = 20x + 40

45 = 15x

x = 3 weeks

2) How much money will that be? plug x = 3 back into the equation to solve for y:

Jake: 5(3) + 85 = $100
Seth: 20(3) + 40 = $100
