all the distances from the curved surface are measured from the:
a) pole
b) centre of curvature
c) focus
d) radius of curvature
plz reply

Respuesta :

Pole is the answer.

Actually when we measure, we use metre scale and thread. But since option doesn't have it, so Pole is the answer . Because all curved surfaces has a pole . So, we can directly measure around it.

Hope it helps you
