A circle is inscribed in `DeltaABC` is tangent to `AB` at `P` and its radius is 21. Given `AP = 23` and `PB = 27`. The Perimeter of the triangle is

In the given figure AP and AQ are tangents to the circle with centre O. BC is tangent at point R on it. If OA=17 cm and radius of the circle =8cm, find the perimeter of the triangle ABC.

In the diagram to the right , the circle with center O is inscribed in equilateral triangle BCD. If the radius of the circle is 4, what is the ratio of the perimeter of triangleBCD to the area of triangleBCD ?

A circle is inscribed in an equilateral triangle. If the in-radius is 21 cm, what is the area of the triangle?

A circle of radius unit is inscribed in a triangle whose two of its sides are along coordinate axes. The locus of the circumcentre of the triangle is

A circle of radius unity is inscribed in an isosceles triangle. The least perimeter of the triangle is :

From an external point P tangents PA and PB are drawn to the circle as shown in the above figure. CD is the tangent to the circle at E. If AP 16 cm, then the perimeter of the triangle PCD is equal to
