Length of arc=4π

Step-by-step explanation:

Length of arc=¤/360 x 2xπxr

Where:

¤=72

r=10

Length of arc=72/360 x 2xπx10

Length of arc=0.2 x 20π

Length of arc=4π

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
