The length of the each side of an equilateral triangle is 28 cm. The area of incircle, (cm ² ) is

In ∆ABC , G is the centroid , AB = 5 cm, BC= 6 cm and AC = 7 cm , find GD, where D is the mid-point of BC?

In ∆ABC, AB = 5cm, BC = 10cm, and AC = 13cm then find out the value of cos A.

The area of an equilateral triangle is 36√3 sq m. Its perimeter is 

In ∆ABC , G is the centroid , AB = 12 cm, BC= 16 cm and AC = 20 cm , find GD, where D is the mid-point of BC?

What will be inradius of a right angle triangle whose base is 12 cm & height is 35 cm ?

In ∆ABC , G is the centroid , AB = 8 cm, BC= 12 cm and AC = 14 cm , find GD, where D is the mid-point of BC?

Let two chords AB and AC of the larger circle touch the smaller circle having same centre at X and Y. Then XY = ?
