The general form of Green's theorem is∫CF⋅dr=∬R(∂Q∂x−∂P∂y)dA By using the given circle equation we have to find the area of the circle and apply in the general form to get a solution. Answer and...
For the circle with radius s, the circumference is equal to 2 * π * s. The arc length of the sector is equal to 2 * π * r. The area of a sector –which is our lateral surface of a cone – is given by the formula: A(lateral) = (s * (arc length)) / 2 = (s * 2 ...
and how to apply this area formula to sectors and pieces of a circle. The angles of a circle are often measured in degrees or radians, and we just need to know how to use these measurements as a ratio to find the area of a sector of a circle or a semicircle.This resource explains ...
