See below: #22m#

Explanation:

To find the cicumference of a circle you need to know the formulae.
#C=pid# formulae
#pi=3.14# usually #pi# is #3.14#
#d=7m# diameter
#C=pi*7#
#C=21.9911485751...#
#C=22m#

I hope this helps!

An approximate answer would be about #3xx 7m = 21m#

Explanation:

If you are looking for an approximate answer, it means we can just do a quick estimate.

The circumference of a circle is found by multiplying the diameter of a circle by #pi#.

The value of #pi# is about #3.142#, but for an estimate we can just use #3#.

For a diameter of #7#, the circumference will be a bit more than #3# times #7#

#3 xx7m =21m#

This would be an approximate value of the circumference.
It will actuallybe a bit more than this.)
