The tool of an $$NC$$ machine has to move along a circular arc from $$(5,5)$$ to $$(10,10)$$ while performing an operation. The center of the arc is at $$(10,5).$$ Which one of the following $$NC$$ tool path commands performs the above mentioned operation?

In a $$2-D$$ $$CAD$$ package, clockwise circular arc of radius, $$5,$$ specified from $${P_1}\left( {15,10} \right)$$ to $${P_2}\left( {10,15} \right)$$ will have its center at

During the execution of a CNC part program block
$$NO20\,\,\,\,GO2\,\,\,\,X45.0\,\,\,\,Y25.0\,\,\,\,R5.0.$$ The type of tool motion will be

In finish machining of an island on a casting with $$CNC$$ milling machine, an end mill with $$10$$ $$mm$$ diameter is employed. The corner points of the island are represented by $$(0,0), (0,30), (50,30)$$ and $$(50,0)$$. By applying cutter radius right compensation, the trajectory of the cutter will be
