An equilateral triangle ABC\mathrm{ABC} is inscribed in a circle of radius 203 cm20 \sqrt{3} \mathrm{~cm}. What is the length of the side of the triangle ?

Correct Option: 4
1) For an equilateral triangle inscribed in a circle:\newline - If RR is radius of circumscribed circle\newline - Then side length a=R3a = R\sqrt{3}
2) Given:\newline - R=203R = 20\sqrt{3} cm
3) Therefore:\newline - Side length = 203×320\sqrt{3} × \sqrt{3}\newline - =20×3= 20 × 3\newline - =60= 60 cm
Therefore, the side length of the equilateral triangle is 6060 cm.
