Dia of Core of circle = d/4.
Dia of Circle = d.

Area of Core/Area of Circle = 1/16 will get.

Thanks @Aswathy.

Radius of circular section = r.
Radius of core section = r/4.
Area of circular section,A1 = πr^2.
Area of core section,A2 = π(r/4)^2 = (πr^2)/16.
Ratio ,A1/A2= πr^2/(πr^2/16) = 16.

Substitute the values in the area formulae.i.e., in CS Area d=2r and in core area d=r/2.

Circular = 1/16.

What formula is used here? Please tell me.

Use the formula = pi r^2.
The radius of core 1/4th of r, So, 4^2 = 16.
