The circumference of circle is 8π ft.

Step-by-step explanation:

Given that the formula of area of a circle is A = π×r² where r represents the radius of circle. So you have to find the radius first :

Next, you have to apply circumference of circle formula, C = 2×π×r :

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)

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
