Question

The thickness of a hollow wooden cylinder is
2 cm. It is 35 cm long and its inner radius is
12 cm. Find the volume of the wood required
to make the cylinder, assuming that it is open
at either end.
​

Answer 1

наверно 29 или 23 но это не точно

Answer 2

Answer:

Thickness of Wooden Cylinder (t)=2 cm

Height of Cylinder (h)=35 cm

Inner radius (r)=12 cm

Outer radius (R) =r+t=12+2=14 cm

Volume of Wood Required = Outer Volume of Cylinder - Inner Volume of Cylinder

=> (π×R

2

×h)−(π×r

2

×h)=π×h(R

2

−r

)

=> 227×35×(196−144)=227×35×52=5720cm

3

=> VolumeofWoodRequired=5720cm
