The distance a piece of insulation would be, would be the circumference of the pipe.
The circumference is found by multiplying the diameter by PI.
Circumference - 3.14 x 2 meters = 6.28 meters
1 meter is equal to 100 cm.
Multiply the total meters by 100 to convert to cm:
6.28 meters x 100 = 628 cm.
The answer would be a. 628 cm.
