The circumference of a circle is the "length" around the circle. The diameter is an imaginary line that you "draw" through the "inside" of the circle that starts from one end of the edge of the circle, goes through the center point of the circle and then ends at the opposite point of the circle from where you began.
The formula for finding circumferences of circles is: circumference=pi x diameter, or c=pi x d (pi is about 3.14 or 22/7)
So to find out the circumference of a circle with diameter 7.3 cm, you would do pi times 7.3, and that'll be your answer. (Don't forget to write "cm" in your answer!)
Hope this helps, and good luck~! ^_~

Since circumference/diameter=pi,
C/7.3=3.14
Multiply both sides by 7.3
C=22.922 (approximately)
Or specifically:7.3pi

C equals Pi times d
C= Circumference
Pi=3.14 (a constant)
d= diameter
C=3.14 x 7.3cm
C=22.922cm

the circumference of a circle is the diameter times pi.
pi is 3.1416 for easy use.
there the circumference of your circle is 7.3 x 3.1416 =22.93368 cm.

The formula is pi*d... so, it's 7.3cm*pi. Pi=3.1416.
So, C= 22.934cm
