A solid is hemisp
Answer :
Given: Bottom of a solid is hemispherical and conical above it, both have same radius
and same surface areas.
∴ CSA of hemisphere = CSA of Cone
⇒ 2 × π × r2 = πrl (where r is the radius and l is the slant height)
⇒ 
= 
⇒
= 
∴ r:l = 1:2
That is ratio of radius and the slant height of the given solid is 1:2.
