pls tell me the formula of finding volume of cylindrical objects with some thickness?

Answer 1

There are many types of cylindrical objects:
Right circular cylinder,An elliptic cylinder ,Cylindrical vessel having different types of dish ends,Horizontal and vertical cylindrical tank/vessel.

1.Right circular cylinder:In common usage, a cylinder is taken to mean a finite section of a right circular cylinder with its ends closed to form two circular surfaces.If the cylinder has a radius r and length (height) h, then its volume is given by,
V=Pi*r^2*h (unit)^3,unit may be m^3,cm^3,......

((V1=Pi*r1^2*h1,where r1=inner radius,h1=Inner height.
V2=Pi*r1^2*h2,where r1=outer radius,h2=h1+2*thickness.(for closed cylindrical.))
For open cylindrical tank,h2=h1+thickness of the bottom.

Answer 2

Perhaps you mean a hollow cylindrical shell and you want to know the volume of the material required to make it. If it is so, then,
Volume = 2*Pi* r* h* t , r = radius , h= height, t = thickness of the walls, Pi =3.142

If you mean that the height of the solid cylinder is small and you are calling this as thickness t, then,
Volume = Pi * r^2 * t

Answer 3

The volume would be the height of the cylinder times the area of the base, measuring the radius of the base from the center to the INNER surface of the wall. If you have the measurement for the radius of the OUTER surface, you must subtract the thickness of the wall.

Answer 4

first take out the radius of the given cylinder.If some thickness is there take out the diameter of the cylinder by the method 2radius+2thickness.Apply this when the internal radius is given.But if the total radius is given then no need for the above method .After finding the diameter half it and your total radius will come.Now to find the volume apply the formula pie*radius*radius*the height of the cylinder,the value of pie is 22/7.

Answer 5

Volume of a cylinder with radius=r, height=h is volume= Pi*r*r*h,
that is product of base area and the height of the cylinder.
Volume of the material required to make the cylinder with thickness 't', where t=(R-r); where R is outer radius & r is Inner radius is = Pi*(R*R-r*r)*h.
Volume of material that can be filled inside the cylinder with inner radius=r, height=h and with any thickness is equal to Pi*r*r*h.
Value of Pi is 3.141592654.

Answer 6

The volume of a cylinder is the area of the base multiplied by the height.

Answer 7

Volume of a cylinder= pie r^2 h
Volume of metal used= outer curved surface area-inner surface area
=pie R^2 h-pie r^2h ( here R is the outer radius and r is the inner radius )
= Pie h (R^2-r^2)
Solve it using the identity a^2-b^2= (a+b) (a-b)

Answer 8

Cylinder with radius r and height h :

Area of curved surface = 2 π r h
Volume = π r² h

Answer 9

formula for volume of cylinder with thickness is
pi*(R^2 - r^2)*h
where pi=22/7 or 3.14
R=bigger radius i.e. radius from centre to the outer edge
r=smaller radius i.e. radius from centre to the rim where thickness starts
h=height
r^2 means r square
R^2 means R square.

Answer 10

Statement of problem: Find volume of a cylindrical PIPE of radius R, height h and thickness t which is hollow inside.
=> outer radius =R
inner radius r=R-t
volume=PI*(R)^2*h - PI*r^2*h=PI*(R^2-r^2)*h=PI*(R-r)*(R+r)*h=PI*(2R-t)*t*h.

get's more complicated with right prisms. a circular right prism is a cylinder.
