WebTo find the arc length, we definitely need the radius of the circle and central angle. But when the radius is not given, then either the sector area or the chord length might have been given. Use the following formulas to solve for the radius and then apply the arc length formula. Sector area = (θ/360º) × πr 2, if θ is in degrees (or) (1/2 ... WebArea outside the triangle = πr² - ¼ a²√3 Because the area of an equilateral triangle is ¼ a²√3 Since a = r√3 also stated as a² = 3r² Substituting, πr² - ¾r²√3 Since r = 2, we get 4π - 3√3 = 7.370 Of course my way does require knowing that a² = 3r² for an inscribed equilateral triangle (though it isn't too hard to derive if you didn't know that) WebFigure 1. formulas for arc Length, chord and area of a sector In the above formulas t is in radians.
