Find the radius of a circle whose circumference is 9pie

1.4 (rounded to the nearest tenth)

1.43 (rounded to the nearest hundredths)

1.432 (rounded to the nearest thousandths)

Step-by-step explanation:

C=2 π r

C/2 π = 9/2 * π = (depends what is is rounded to really)

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
