someone please help

OpenStudy (welshfella):

line 9 comes after line 3 then you need to find a line giving the value of r then proceed to find the circumference

OpenStudy (anonymous):

So are these right? @welshfella

OpenStudy (welshfella):

No - after r^2 = 196 you need to take the square root of each side to find what r is ( 2 steps need to be inserted after the step r^2 = 196)

How about now? @welshfella

OpenStudy (welshfella):

thers just one out of place its after you have taken the square roots of r^2 and 196
