If the area of the circle is `A_1` and the area of the regular pentagon inscribed in the circle is `A_2,` then find the ratio `(A_1)/(A_2)dot`

Find the area of regular polygon ? If the area of the circle is A_(1) and area of a regular pentagon inscribed in the circle is A_(2); then find the ratio (A_(1))/(A_(2))

If the area of circle is A_(1) and area of regular pentagon inscibed in the circle is A_(2), then find the ratio of area of two.

In the circuit of figure A_1 and A_2 are ideal ammeters. Then the reading in ammeter A_2 is

A regular pentagons is inscribed in a circle. If A_(1) and A_(2) represents the area of circle and that of regular pentagon respectively, then A_(1) : A_(2) is

A circle is inscribed inside a regular pentagon and another circle is circumscribed about this pentagon.Similarly a circle is inscribed in a regular heptagon and another circumscribed about the heptagon. The area of the regions between the two circles in two cases are A_1 and A_2, respectively. If each polygon has a side length of 2 units then which one of the following is true?

The capacitance of the capacitors of plate areas A_1 and A_2(A_1 lt A_2) at a distance d is
