Bianca filled 2 same-sized jars with flavored popcorn as a gift. She wants to glue a piece of ribbon around the edge of each lid.

The radius of each jar lid is 5 centimeters. Approximately what is the total length of ribbon she will need for the two jar lids? (Use 3.14 for \(\pi\).)

A. 157 cm
B. 78.5 cm
C. 31.4 cm
D. 62.8 cm

Answer :

To calculate the total length of ribbon needed for the two jar lids, we need to find the circumference of one lid and then multiply it by 2 (since there are two lids).

The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

Given that the radius of each jar lid is 5 centimeters, we can calculate the circumference of one lid:

Circumference of one lid = 2 × 3.14 × 5 cm ≈ 31.4 cm

Now, to find the total length of ribbon needed for the two jar lids, we multiply the circumference of one lid by 2:

Total length of ribbon = 31.4 cm × 2 = 62.8 cm

Therefore, the total length of ribbon Bianca will need for the two jar lids is approximately 62.8 cm.

The correct answer is:

D. 62.8 cm
