WebStart with the formula: Area of sector = 1⁄2r2θ Don't forget:r2= r × r (r squared). 2 Substitute the angle and the radius into the formula. In our example, θ = 2 and r = 5. … WebArea of a sector = (θr2)/2 Where θ = the measure of the central angle given in radians. Area of a sector given the arc length Given the length of the arc, the area of a sector is given by, Area of a sector = rL/2 Where r = radius of the circle. L = arc length. Let’s work out a couple of example problems involving the area of a sector. Example 1
4.3: Area of a Sector - Mathematics LibreTexts
WebIf you know the arc length and the radius, then the angle that is subtended by the sector is θ = L / r where L= arc length and r = radius (Angle in radians, of course.) Thus, the area of the sector would be: A = (θ / 2π) … WebSector of a Circle Calculus Absolute Maxima and Minima Absolute and Conditional Convergence Accumulation Function Accumulation Problems Algebraic Functions Alternating Series Antiderivatives Application of Derivatives Approximating Areas Arc Length of a Curve Area Between Two Curves Arithmetic Series Average Value of a Function how to spell the name julia
