ok guys
suppose a body or something with radius of more than or equal to 3X10^8 meters is rotating at speed of 90 degree /sec : then a point at crust of top layer will travel at speed of 3√3 X10^8 m/s (using pythagoras theoram ) so have i done anything wrong please correct me ? thank you

Arithmetic may be correct, but it would be physically impossible.
