What is the ratio of the base-radius and slant height of a cone made by rolling up a semicircle?

Answer»

Radius of bigger circle = R

Radius of smaller circle = r

Radius of circular base of the pyramid = r = \(\frac{R}{2}\)

Ratio between radius and slant height 

\(r\div R=\frac{R}{2}:R=\frac{1}{2}:1=1:2\)
