How can there be so much to do over such a simple problem?
Centrifugal acceleration equals the square of the angular velocity times the 
radius.
Angular velocity is in radians per second and is gotten from rpm by 
multiplying by 2PI
and dividing by 60.  With the radius in cm the result is in cm/sec/sec.  
Dividing by
g of 980 cm/sec/sec gives the equivalent g.  This is a simple scientific 
calculator
operation.  Who needs to look up a formula?
