The formula for circumference = 2
$\pi$ r
Therefore we know that 25.12= 2
$\pi$ r
To find the value of the radius, we divide 25.12 by 2
$\pi$ .

$(25.12)/(2 \pi )$ = 3.9979721705 or approximately 4ft.
In this case, 8ft would be the diameter instead of the radius.

Kate says the radius of the circle is 8 feet. What is Kate's error?
