Question

If the outside diameter of a pipe is 2 m, the length of a piece of insulation wrapped around it would be a)- 628 cm b)- 12.56 m. c)- 12.56 cm d)-62.8 m

Answer 1

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.
