The circumference of a circular garden is 87.92 feet. What is the radius of the garden? Use 3.14 for (pie symbon inserted here) and do not round your answer.

Question

anonymous · Answer

87.92=2*pi*r, plug in pi and solve for r

anonymous · Answer

Circumference C = 2*pi*r.  To solve, let C = 87.92 and let pi = 3.14.  Then you will be able to solve for r (the radius).  Good luck!

anonymous · Answer

So, 87.92=2(3.14) 87.92/2 ?

anonymous · Answer

1. C = 2*pi*r
2. 87.92 = 2*(3.14)*r
3. 87.92/(2*3.14) = r
4. r = radius

anonymous · Answer

This makes no sence

anonymous · Answer

The equation for circumference is C = 2*pi*radius.  You are given the circumference (C) and we know that pi = 3.14.  The only variable you have left to find using simply math is the radius r.   Does that help?
