Question

a solid is in the shape of a cone mounted on a hemisphere of same base radius of a hemisphere and the conical Part are equal then find the ratio of radius and the height of the conical part​

Answer 1

first take the ratio of the surface area of the cold and surface area of the hemisphere that is

$2 \pi {r}^{2} \binom{.}{.} \: \pi {r}^{1}l$

$2r \binom{.}{.} l$

so their ratio is 2:1 respectively
