Answer:

L = 29,550 mm (as per BS8110 the length is to the nearest 25)

Explanation:

Lets make it so simple and easy.

Let A = 600mm

Let B = 300mm

Let C = 16 as number turns

Let d = 20mm

L =
$\sqrt{(3.14 * (600 - 20))^(2) + 300^(2)$ x 16

L = 29,550 mm (as per BS8110 the length is to the nearest 25)
