WebHere are the steps to find the area of a segment of a circle. Identify the radius of the circle and label it 'r'. Identify the central angle made by the arc of the segment and label it 'θ'. Find the area of the triangle using the formula (1/2) r 2 sin θ. Find the area of the sector using the formula (θ / 360 o) × πr 2, if 'θ' is in degrees (or)
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) polygon features是什么意思WebThe area of a circle with an angle measuring 360º at the center is given by πr 2, where 'r' is the radius of the circle.
