WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. WebBecause 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) Comment.
