Question

elizabeth buys a circular rug with a lace border. the lace is 12.56 feet long what is the diameter of the rug

Answer 1

We know that the lace is also what we would call the circumference of the circle.

And we also know that the circumference of a circle is represented by the equation: $c= \pi d$.

We then can use the length of the lace (12.56 ft) to solve for the diameter (d) of the rug. Let us solve for that now:

$12.56=(3.14)d$

$d=4$

We now know that the diameter of the rug is 4 ft.

Answer 2

4 feet is the correct answer.
