A solid is hemispherical at the bottom and conical above. If the surface areas of the two parts are equal, then the ratio of its radius and the height of its conical part is `1\ :3` (b) `1\ :sqrt(3)` (c) `1\ :1` (d) `sqrt(3)\ :1`

A solid is hemispherical at the bottom and conical (of same radius) above it . If the surface areas of the two parts are equal then the ratio of its radius and the slant height of the conical part is

A solid is hemispherical at the bottom and conical above. If the surface areas of the two parts are equal, then the ratio of radius and height of its conical part is एक ठोस तल पर अर्द्ध गोलाकार है और ऊपर शंक्वाकार। यदि दोनों भागों के पृष्ठ क्षेत्रफल बराबर है, जो उसके शंक्वाकार भाग की त्रिज्या और ऊँचाई का अनुपात है-

A solid is in the shape of a cone mounted on a hemisphere of same base readius. If the curved surface areas of the hemisphere part and the conical part are equal then find the ratio of the radius and the height of the conical part.
