Step-by-step explanation:

Its a 1 mark question, easy to understand

Answer 2

Answer:

root2:1

Step-by-step explanation:

the volume of cylinder is

$\pi {r}^{2} h$

here r = radius, h= height

have height in ratio 1:2 means 3.14×r×r×(1) : 3.14×ŕ×ŕ×(2)

r×r : 2ŕ×ŕ

$\pi {r}^{2}h$

r:ŕ =

$\sqrt{2 } \div 1$
