Question

Both a cone and a solid cone have equal
radii (r) and equal height (h) The volume
of each of them is​

Answer 1

Answer:

Answer

For cylinder, we have

base radius=r, height=h

∴S1=Curved surface=2πrh

For cone, we have

l=r2+h2 and, S2=πrl=πrr2+h2

We have,

S2S1=58

⇒πrr2+h22πrh=58

⇒r2+h22h=58

⇒r2+h24h2=2564

⇒25h2=16r
