Do you know the formula for the area of a circle? A= pi radius(squared) We know: 28 = 3.14159265 r(squared), where we just want to know 'r', the radius. Can you figure it out from here?
OpenStudy (asett):
No, @benito893764. not quite! You forgot to take the square root. :)

Not quite. First, divide 28 by 3.14159265 (which is pi). This equals approx. 8.9, right? Can you take the square root of that to get your answer?
