The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter.

Given that the diameter is 8 kilometers, we can substitute this value into the formula:

C = 3.14 * 8

C = 25.12

Therefore, the circumference of the circle is approximately 25.12 kilometers.

The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference and r is the radius.

Given that the radius is 3 feet, we can substitute this value into the formula:

C = 2 * 3.14 * 3

C = 18.84

Therefore, the circumference of the circle is approximately 18.84 feet.
