## What is the formula for finding the angle in the development of cone?

To calculate the dimensions of the development, first the slant height of the cone must be found from Pythagoras’ theorem, ie R = √ [ H^2 + ( D/2 )^2]. The sector angle θ is found from the formula θ = D x ( 180 / R ), which gives θ in degrees.
