Answer 1

the formula for calculating the circumference of a circle is:

`2\pi * r`

where r is the radius

or you can use this other formula:

`\pi * d`

where d is the diameter of the circle.

for your answer using the first formula

=2×pi×r

=2×pi×7

=43,98 m

your answer using the second formula

=pi×d

=pi×14

=43,98 m
