Finding area of a circle sector
WebA sector of a circle is the proportion of a circle where two of the sides are radii. An arc length of the sector is the proportion of the circumference which runs the length of the sector of the circle. If the angle at the centre of the circle is in degrees, the formula for finding the area of the sector is: π θ A r e a o f a s e c t o r = π ...
