Question

The height h of water in a cylindrical container with radius r = 5 cm is equal to 10 cm. Peter needs to measure the volume of a stone with a complicated shape and so he puts the stone inside the container with water. The height of the water inside the container rises to 13.2 cm. What is the volume of the stone in cubic cm?​

Answer 1

Answer:

∴Volume of the stone = 80π cm³

Step-by-step explanation:

Given , Cylinder with  r= 5 , h= 10

∴ Volume of water in Cylinder Container  = πr²h

= π x 5 x 5 x 10

= 250π cm³

Height of Water after stone is immersed = 13.2 cm

∴ New Volume = πr²h

= π x 5 x 5 x 13.2

= 330π cm³

∴Volume of the stone = New Volume of Cylinder -  Volume of water in Cylinder Container

= 330π cm³ - 250π cm³

= 80π cm³
