WebArea of a sector. The formula for the area of a sector is (angle / 360) x π x radius, but the diameter of the circle is d = 2 x r, so another way to write it is (angle / 360) 2 x π x (diameter / 2).Visual on the figure below: Since a … WebYou ask why there is a division by 2. I'm assuming here that there is an acceleration of 3 m/s 2 then. If you have a linear acceleration, starting from v=0, the area under the curve is just a triangle with a right angle. The area of such a triangle can be calculated by 1/2*width*hight, this is why you have a factor 1/2. Is that indeed your ...
