(urgent ) use pi 3.14 to estimate the circumference of the circle to the nearest hundredth middle is 4in (urgent )

12.56in

Step-by-step explanation:

Diameter=4=d

circumference of a circle=×d

                                         =×4

                                         =3.14×4

                                          =12.56

12.56in

Step-by-step explanation: The Formula of a circle for the circumference is 2*3.14=3.14*d.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
