Question

35. There is some water in a cylindrical vessel of radius 7.2 cm. The surface of water increases by 5 cm
when a cylinder of radius 4 cm is immersed in it. Find the height of immersed cylinders . please explain step by step correct answer in marked as BRAINLIEST ​

Answer 1

Answer:

Volume of cube

<br> Diameter of vessel (2r) = 11 cm <br>

<br> Let the surface of water increases = h cm <br>

Volume of Now, volume of displaced water = volume of cube <br>

<br>

<br>

The increase in the surface of water = 1.75 cm

Answer 2

Answer:

Increase in volume of cylinder = volume of sphere

Let increase in volume of cylinder be =πrSquare

h, where r is its radius and h is its height.

So, πrSquareh= 3/4πrCube

⇒16πh= 3/4πCubewhere radius of the cylinder=4cm and radius of the sphere=3cm

⇒h= 3/4× 16/27 = 16/36 = 4/9 = 2.25cm

∴ water rises by 2.25cm in the vessel . (Answer)
