In order to give the correct answer to the question of the task, you need to know the formula for finding the circumference.
The circumference is equal to: P = 2PR, where P is the circumference, P is the number pi, equal to 3.14, R is the radius.
1) With a radius of 31 dm.
P = 2 * 3.14 * 31 = 194.68 dm.
2) With a radius of 200 cm.
P = 2 * 3.14 * 200 = 1256 cm.
3) With a radius equal to 3200 mm.
P = 2 * 3.14 * 3200 = 20,096 mm.
