Approximately, the amount of ribbon you will need around the circular rug is: B. 26 feet.

Recall:

  • Circumference of a circle = distance around the circle
  • Formula for circumference of circle = 2πr, where r is the radius.

Thus, given that the circular rug is 4 feet, the amount of ribbon you will need round the rug = the circumference of the circular rug.

  • Therefore:

Circumference of the circular rug = 2 × 3.14 × 4

Circumference = 25.12 feet

Thus, approximately, the amount of ribbon you will need around the circular rug is: B. 26 feet.
