Answer:

[tex]Diameter=126.12 units[/tex]

Step-by-step explanation:

The circumference of a circle is the length of the boundary of the circle that can be find  by using the formula:

Circumference=[tex]2\pi r[/tex]

For, Circumference= 396 units

As, [tex]\pi =\frac{22}{7}=3.14[/tex]

             [tex]396=2\pi r[/tex]

            [tex]396=2*3.14*r\\\\396=6.28*r\\\\r=396/6.28\\\\r=63.06units[/tex]

As,

           [tex]Diameter=2*radius=2*63.06[/tex]

           [tex]Diameter=126.12 units[/tex]
