Answer 1

Answer:

301.44 mm

Step-by-step explanation:

Diameter of the inside ring of a packing tape = 80 mm

The tape surrounding the ring is 8 mm beyond the ring which means the diameter of the ring including the surrounding will be:

80 + 8 + 8 = 96 mm

and its radius will be = 96/2 = 48.

To find the distance around the outer edge of the tape, we need to calculate the circumference for the ring with the tape on it.

Circumference = $2\pi r$

Circumference = 2 x 3.14 x 48 = 301.44 mm

Therefore,  the distance around the outer edge of the tape is 301.44 mm.
