Gina is adding a lace border to a circular pillow. The radius of the pillow is 8 inches, and she needs to decide how much lace to buy. Which length represents the least amount she can buy?
1) 26 inches 2) 51 inches
3) 101 inches 4) 202 inches

p=2pir
p=2pi8
p=16pi
p=50.2
I would pick 2) 51 inches
Is this correct?

  1. Right.

  2. I will guess the length of the lace shall be larger than 51. It shall be larger than twice of the circumference. So I would say (3) 101.
