Explanation:
Basically, a pully is in the shape of a cylinder
So, if we start from a point of the pully and end at the same point we have calculated the C.S.A. of the pully (cylinder),which is equal to 1 rotation.
So, to find the depth of the well, we would have to find CSA × no. of rotations.
Is this the explaination you needed?
