PLEASE ANSWER!
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 pi.)

51 centimeters

Step-by-step explanation:

first you square the radius, and multiply by pi or 3.14 :)

6.25 grams

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
