Answer 1

Answer:

A. 22.6π

Step-by-step explanation:

Given:

22.6 inches across = diameter

What we need to find is how much ribbon do we need, so we use the formula:

C = 2πr

C = Circumference

r = radius = half diameter

Since we know the diameter, we do half of it to get the radius

22.6 ÷ 2 = 11.3

radius = 11

Now we substitute this into the formula:

C = 2πr

Substitute radius into formula

C = 2π(11.3)

Multiply 2 and 11.3

C = 22.6π

Answer 2

Answer:

45.2pi inches

Step-by-step explanation:

C=2×pi×r

since the answers already have pi we don't need to multiply it

C=2×22.6 = 45.2pi inches
