The circumference of circle A is approximately 106.76 kilometers, the circumference of circle B is approximately 200.96 inches, the circumference of circle C is approximately 122.46 meters, and the circumference of circle D is approximately 157 miles.
The circumference of a circle is the total distance around its edge. It can be calculated using the formula c = 2πr, where c is the circumference, π is pi (approximately 3.14), and r is the radius of the circle.
In the image, the radius of each circle is provided next to it. Here are the circumferences of each circle:
Circle A: 17 km * 2 * 3.14 ≈ 106.76 km
Circle B: 32 in * 2 * 3.14 ≈ 200.96 in
Circle C: 39 m * 2 * 3.14 ≈ 122.46 m
Circle D: 25 mi * 2 * 3.14 ≈ 157 mi
