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

Sagot :

Answer: D. 62.8 cm

Explanation:

Since the radius of each jar lid is 5 centimeters. The total length of ribbon that's needed for each jar lids will be:

= 2πr = 2 × 3.14 × 5 = 31.4

Therefore, the total length of ribbon that she will need for the two jar lids will be gotten by multiplying 2 by 31.4cm. This will be:

= 2 × 31.4

= 62.8 cm
