attachment]

Formula for Circumference of a Circle:-

Where
- C = circumference
- π = pi (3.14…)
- r = radius, which in this case is equal to 8
Substitute the value of r and solve:-

On simplification,
C=16π
On further simplification,
C=50.3
Therefore, we conclude that the circumference of this circle is
