Two legs of a right triangle are `8sqrtpiand9sqrtpi` as shown. A circle is drawn so that the area inside the circle but outside the triangle equals the area inside the triangle but outside the circle. The radius of the circle is `(Use pi=22/7)`

Which of the following numbers is inside the circle but outside triangle and square ?

An equilateral triangle has one of its side coinciding with the diameter of the unit circle. The area of the region inside the triangle but outside the circle is

The perimeter of an equilateral triangle is equal to the circumference of a circle. The ratio of their areas is (Use pi = (22)/(7) )

ABC is a triangle.Circles with radii as shown are drawn inside the triangle each touching two sides and the incircle.Find the radius of the incircle of the Delta ABC.

A circle has been drawn around a rectangle of sides 6cm and 8cm, then find the area of the region inside the circle and outside the rectangle.

A square is made inside the circle. Find the area of that portion of the circle which is not inside the square, if the radius of the circle is 10 cm. ( pi = 3.14 )
