The half of the circumference of the circle, which is 12×2πr=πrfrac{1}{2} times 2pi r = pi r21×2πr=πr.

To find the perimeter of a semi-circle, we need to consider two parts:

The half of the circumference of the circle, which is $frac{1}{2} times 2pi r = pi r$ .
The diameter of the circle, which is $2r$ .

Calculate the curved part (half of the circumference):
$text{Curved part} = pi times r = pi times 700 approx 3.1416 times 700 approx 2199.12 , text{m}$
Add the diameter:
$text{Diameter} = 2 times r = 2 times 700 = 1400 , text{m}$
Total perimeter:
$text{Perimeter} = text{Curved part} + text{Diameter} = 2199.12 , text{m} + 1400 , text{m} = 3599.12 , text{m}$
Convert the result to kilometers:
$3599.12 , text{m} = 3.6 , text{km}$
