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.)
