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 4 centimeters. Approximately what is the total length of ribbon she will need for the two jar lids? (Use 3.14 for .)
A.
50.24 cm
B.
12.56 cm
C.
25.12 cm
D.
100.48 cm
Its 50.24!!!
agree with 50.24
To find the total length of ribbon needed for the two jar lids, we need to calculate the circumference of each lid and then sum them up.
The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius
Given that the radius of each jar lid is 4 centimeters, we can substitute this value into the formula:
Circumference = 2 * 3.14 * 4
Calculating this, we have:
Circumference = 25.12
Since Bianca wants to glue a piece of ribbon around the edge of each lid, we need to find the total length of ribbon for two lids. Therefore, we need to multiply the circumference by 2:
Total length of ribbon = 25.12 * 2
Calculating this, we have:
Total length of ribbon = 50.24 cm
So, the total length of ribbon that Bianca needs is 50.24 cm, which corresponds to option A.
