Solution:
Given that equilateral triangle is bent into a circle.
Therefore, perimeter of triangle has to be equal to the circumference of the circle.
Perimeter of an equilateral triangle = 3 × side
= 3 × 6.6
= 19.8 cm
& since circumference of circle = π × diameter
Therefore, π × dia = 19.8
or dia = 6.30 cm
Hence, diameter of the circle is 6.30 cm.
Hope you got it!
