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 acceleration of a car moving in a circle with uniform speed is directed towards the center of the circle and is called centripetal acceleration. This acceleration is given by the formula a = v^2/r, where v is the speed of the car and r is the radius of the circle.
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
The area ( A ) of a circle can be expressed as ( f(r) = \pi r^2 ). If we substitute ( r = 3 ) into this equation, we get ( f(3) = \pi \times 3^2 = \pi \times 9 ). Thus, ( f(3) \approx 28.27 ) when using ( \pi \approx 3.142 ).
