Answer :
To find the circumference of a circle given its diameter, we use the formula for the circumference:
[tex]\[ C = \pi \cdot d \][/tex]
where:
- \( C \) is the circumference,
- \( \pi \) (pi) is a mathematical constant approximately equal to 3.14159,
- \( d \) is the diameter of the circle.
Given that the diameter (\( d \)) of the circle is 16 kilometers, we substitute this value into the formula:
[tex]\[ C = \pi \cdot 16 \][/tex]
Thus, the circumference is:
[tex]\[ C = 16\pi \, \text{kilometers} \][/tex]
This is the exact expression for the circumference in its simplest form. The approximate numerical value for this expression is 50.26548245743669 kilometers. Hence, the precise answer is:
[tex]\[ 16\pi \, \text{kilometers} \][/tex]
