an equilateral triangle is inscribed in a circle.if length of arc abc = 24..wat is the approx dia of the circle.
ans = 11
ans = 11
Arc abc extends an angle of 360*2/3 = 240 degrees in the center of the circle.divya23 wrote:an equilateral triangle is inscribed in a circle.if length of arc abc = 24..wat is the approx dia of the circle.
Hence, perimeter of the circle = (24/240)*360 = 36
Hence, diameter of the circle = 36/pi = 36*7/22 = 126/11 ≈ 11
