The inside ring of packing tape has a diameter of 80 mm. The tape surrounding the ring is 8 mm beyond the ring. What is the dist

Nutka1998 [239]

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.

<em>Circumference = $2\pi r$ </em>

Circumference = 2 x 3.14 x 48 = 301.44 mm

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