It can be calculated based on a trapezoid. For example, the height of the tower is 65 meters and the radius of the base is 3 meters. It can be seen that its circumference is 2πr=18.84. The radius of the top of the tower is 1.5 meters. It can be seen that its circumference is 9.42 and its area is (9.42 +18.84)×65/2=918.45㎡
171 meters. The diameter of the 6-megawatt wind power tower is 171 meters. Wind power generation refers to converting the kinetic energy of wind into electrical energy.
