The radius of the base of a cylindrical wooden block is 5 cm and its volume is 1100 cu cm. How many discs of radius 5 cm and height 2 cm can be cut from this block of wood?

For the Larger cylinder let the

base radius be ‘R’ = 5cm

height be ‘H’ = X cm

Volume V = 1100 cm

⇒ Volume of cylinder V= Area of circle at bottom × height

H=14cm

Let Height of each smaller cylinder is h

∴ Number of discs of height h

We can cut 7 discs from this block.
