Question 634498
Damon measure the circular pool in his back yard so he could order a cover for it. He found that it had a radius of 8ft and a circumference of 16ft. Can you tell whether he made a mistake in measureing? 
How do I find out if he is wrong or not?
-----
If the radius is 8 ft. 
the circumference is 2*pi*r = 16pi is approximately 50.27 ft.
