<u> P = 2(L +W)</u>
Divide each side of the equation by 2 : P/2 = L + W
Subtract W from each side : <em> P/2 - W = L</em>
Answer: 14.32 degrees
The circle has a diameter of 8 kilometers, so the perimeter would be:
perimeter= pi * diameter
perimeter= 22/7 * 8 kilometers= <span>25.14 kilometers
A full perimeter </span>of the circle, which is 25.14km, has 360° angle. So 1km arc would be: 1km/ 25.14 km * 360°= 14.32°
