Question

If the radius of two hemispheres is in ratio 5:2, find the ratio of their volumes. *

Answer 1

Step-by-step explanation:

Consider the given ratio of hemisphere

r

1

:r

2

=3:5

We know that the curved surface area of the hemisphere

=2πr

2

So, the ratio of curved surface area of hemisphere

=

2πr
