15.7 inches of ribbon are needed.
Solución
We use the formula for the circumference of a circle:
\[
C = \pi d
\]
Substitute the given diameter \( d = 5 \) inches and \( \pi = 3.14 \):
\[
C = 3.14 \times 5
\]
\[
C = 15.7 \text{ inches}
\]
Thus, \(15.7\) inches of ribbon are needed.

To find the length of ribbon needed to go once around the rim of the vase, we’ll calculate the circumference of the circle. The formula for circumference is \( C = \pi \times d \), where \( d \) is the diameter. Here, the diameter is 5 inches. So, using \( \pi \) as 3.14: \( C = 3.14 \times 5 = 15.7 \) inches. Therefore, you will need 15.7 inches of ribbon to go around the rim of the vase!
