Mandy wants to put some lace trim around the outside of a round tablecloth she expanded the original tablecloth had a radius of 2 feet and a circumference of 12.56 Ft if the tablecloth now has a radius of 3 ft is 15 ft of lace enough explain

Question
Answer:
To determine if the amount of lace is enough to be placed around the tablecloth, we determine the circumference of the tablecloth through the equation,
      C = 2πr

where C is circumference,
        r is the radius

Substituting the known values,
    C = 2π(3 ft) = 18.85 ft

Hence, the 15 ft lace will not be enough for the tablecloth.
