Area of a Sector Formula The area of a sector of a circle where the central angle is indegreesis: \[ A = {\theta \over 360} \pi r^2 \] The area of a sector of a circle where the central angle is inradiansis: \[ A = {\theta \over 2} r^2 \] ...
Mathematics - Metric Geometry53A0453A0551N20Three linearly dependent and pairwise linearly independent vectors of an euclidian space uniquely determine a planar quadric with symmetry centre in the origin. A rather simple formula for the area of an arbitrary sector at centre of such a quadric will...
Area of Sector = A = (θ) ×πr2 A = (L/r) × (r2/2) A = (L × r)/2 Perimeter Formula for a Sector As we know that perimeter refers to the summation of the length of boundaries of any geometrical shape. Using the same concept, we can derive the formula for the perimeter...
Area of a Sector = ( $\frac{\theta}{360}$) π r2 where $\theta$ = central angle in degrees, and r = radius of the sector. Area of a sector given the central angle in radians Recall that radians are based on π (a circle is 2π radians). The following formula is used if the...
