find the circumference of 7

The circumference of a circle is calculated using the formula:

circumference = 2 * π * radius

Given that the radius is 7 units, we can plug this into the formula:
circumference = 2 * π * 7

Calculating this gives:
circumference = 14π

Therefore, the circumference of a circle with a radius of 7 units is 14π or approximately 43.98 units.
