From 7:00, when Mitch starts explaining how to find the length, you dont actually have to calculate the angle and then multiply it with the radius but the method is similar. You could use the theta equation (theta = lambda/b) and implement it in the length equation (length = radius * theta) to form the equation (length = radius * lambda/b). Substitute the values and multiply the answer by two.

hello sir, when we calculate the width of the central max, you used the formula: l = r*theta, but could you also use tan (theta) = 1/2 of the central max over 3.5m?

but doesnt r(theta) give you a curved length? should we not use the trig formulas instead?
