The length (l) of the circle is 2 * n * r. l = 2 * n * r. n = 3.14.
Find the length of the first circle:
l1 = 2 * 3.14 * 0.75 = 4.71 m.
Find the length of the second circle:
l2 = 2 * 3.14 * 35 = 219.8 cm.
find the length of the third circle:
l3 = 2 * 3.14 * 25 = 157 mm.
Answer: l1 = 4.71 m, l2 = 219.8 cm, l3 = 157 mm.
