Question

Find the area of the shaded region triangle abc is equilateral triangle having radius of circle 16

Answer 1

In an equilateral triangle inscribed in a circle, the area of the triangle is given by :

[3 r^2 * sqrt(3)] / 4 (See: Formulas for Polygons and Circles)

Area of triangle = [3 * (10^2) * sqrt(3)] / 4

= [3 * 100 * sqrt(3)] / 4

= 75* sqrt(3)
