I think I got this one right, just want to doublecheck is all. Thanks in advance!
A plane is flying in a loop to simulate weightlessness for a brief instant. If the speed is 215m/s, what is the radius of the circle?
I have since v = sqrt rg where v is velocity, r is the radius, and g is gravity, that it comes out to (215^2)/9.98 = 4631.7635m
Did I do this correctly? If not, please explain what I did wrong and get me on the right track. Thanks!

If the formula is correct, your calculation is correct but you may consider taking the value of g as 9.8 m/sec^2 instead of 9.98

For the centrifugal force to cancel the force of gravity at the top of the loop, you have:
m*v^2/r=mg
Therefore r=v^2/g and your answer is correct.
