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]
