Question

Maddie needs to construct multiple rings for a tournament using twine to mark the circumference of each ring. If she has 150 feet of twine, what is the maximum number of full rings Maddie can make?

Answer 1

Answer: the correct answer is 4 rings and she has 7.74 feet of twine left over.

Explanation:

For each ring she needs 10Pi feet of twine = 10* 3.1416 =31.42 feet

She has 150 feet; 150/31.42 = 4 rings and she has 7.74 feet of twine left over
