Question

please slove above ⬆given question.........

Answer 1

From the question it is quite clear that radius of the sphere = radius of the cylinder and the diameter of the sphere = height of the sphere .

Let the radius of the sphere be r units .

→ radius of the cylinder = r units

and , height of the cylinder = 2r units.

1) r:r =1:1

2) 2πr×2r /4π r^2 = 1:1

3) πr^2×2r /( 4/3 π r3)

=3:2
