Question

F) A wire is bent to form A ABC such that AB = 6.6 cm, 2C = 60°. AC = BC.
Now a circle is formed by the same wire then find the area of the circle.
तर/Ans:​

Answer 1

2pi r = 3 * 6.6 ( the triangle is equilateral as two sides are equal and the included angle is 60 degrees ...thus the other angles are also 60 .. 0

r =3* 6.6*7\22*2

  =  

area = pi r^2

        = 22\7  * 9.925

         = 31.185 cm^2
