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))

The area of a circle is A 1 and the area of a regular pentagon inscribed in the circle is A 2 ​ . Then A 1:A 2 ​ is

The area of a circle is A_(1) and the area of a regular pentagon inscribed in the circle is A_(2) . Then A_(1)//A_(2) is

If A, A_1,A_2,A_3 are the areas of the inscribed and escribed circles of a DeltaABC, then

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?

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?

A circle with area A, is contained in the interior of a larger with area A_1+A_2 . IF the radius of the larger circle is 3 units and A_1,A_2 and (A_1+A_2) are in A.P., then find the radius of smaller circle…..

If the whole surface area of a right circular cone be A_1 sq- unit andif its curved surface area be A_2 sq-unit, then the area of the base is (A_1-A_2) sq-unit.
