I want to make a cone funnel with diameter D1 = 80cm, diameter D2 = 30cm and height h = 40cm. Please help me to draw a fan-shaped diagram? The radius of the large arc is R1, the radius of the small arc is R2, and the center angle of the arc is a.r1-r2 = (H ^ 2 + ((d1-d2) / 2) ^ 2) ^ 0.5 = (40 ^ 2 + ((80-30) / 2) ^ 2) ^ 0.5 = 47.1699a = P
