The next one.
Please go on. What is "circle F" ? And what are the choices ? This has all become quite mysterious.
Such a circle is impossible. The radius of a circle is half its diameter.

The 2001 Ford F-150's turning circle is 40.5 ft..
The 2005 Ford F-150's turning circle is 41.8 ft..
The 2006 Ford F-150's turning circle is 41.8 ft..
f=ma centripetal force= mvsquared/radius so centripetal acceleration=vsquared/radius
F=(MV2)/R Where F is centripetal force, M is the mass of the object, V is the straight-line velocity of the object and R is the radius of the circle it is travelling in.
It is the area of a circle because pi*32 = 28.274 square units to 3 decimal places.
It doubles too. The diameter is always twice the radius. Multiplying either of the two by any factor f automatically multiplies the other one by the same factor.
If an object moves in a circular path it goes faster when the radius gets smaller according to the equation of circular motion F=mv^2 /r
