Question

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 3 centimeters. Approximately what is the total length of ribbon she will need for the two jar lids? (Use 3.14 for .)

Answer 1

Answer:

37.68cm of ribbon

Step-by-step explanation:

This question is asking you to find the circumference of the two lids. To find circumference all you have to do is multiply the diameter (the radius times 2) by pi.

If the radius is 3 then the diameter of the lid is 6 because of 2*3=6. Now all you hade to do is multiply 6 and 3.14.

6*3.14=18.84.

This is the amount of ribbon you need for just one of the jars but you have a second jar so you would need to multiply this by 2 to get the total amount needed.

18.84*2=37.68
