Answer 1

Hi dear your answer is =

Volume of sphere = 4/3πr³

Volume of cylinder = πr²h

A.T.Q.
4/3πr³ = πr²h
4/3r = h
4/3 = h/r

Now,
C. S. A of cylinder = 2πrh

surface area of sphere = 4πr²

RATIO= 2πrh/4πr²
h/2r

4/3*2

2/3.

Answer = 2:3.

it will completely help.

u will understand dear.
mark as brain list.
