Formula to find volume of the cylinder?

Answer 1

Volume of cylinder

A cylinder has a round base and a given height. The area of the base must be found first, and then it can be multiplied by the height to give the volume of the cylinder.

The area of the base is given by taking the radius (r) of the circular base and squaring it and then multiplying it by pi.

Areabase = pi r2

Then multiply that by the height (h) of the cylinder to get the volume.

Volumecylinder = pi r2 h

The volume of a cylinder is pi times the square of the radius of the base times the height of the cylinder.

Use the link below for more information and a slightly different presentation. Also note that there are some "variations on the theme" as regards the shape of a cylinder. The classic shape is a "right circular cylinder" as shown in the diagram in the Wikipedia post. But we can depart from there in more advanced applications.

Example:

Find the volume of a cylindrical canister with radius 7 cm and height 12 cm.

Solution:

1847.5 cm3

Volume of cylinder = π x r x r x h

Where π = Pie , r = radius of cross section f cylinder and h = height of cylinder
(assuming it to be a Right Circular Cylinder)

Answer 2

The formula for Cylinder:

If we have a cylinder with the radius r, n is 3.14, and height h, the volume V of the cylinder is: V = πr2h

Answer 3

Volume: 4/3πr3

Surface area: 4πr2

hope this helps :)

Nope....Cylinder volume is πr2 x height or πr2h

(π=pi ....just in case the font makes it look like an "n")

You have the one for a sphere there

Surface area is 2πr2 + 2πrh....may not be the official formula, but I promise it works

Answer 4

You need to know: 'R' = the radius of the end of the cylinder; it's 1/2 the diameter 'H' = the height (or length) of the cylinder pi = a number, approximately 3.14159 'R' and 'H' need to be both in the same units ... inches, feet, meters, etc. The volume of the cylinder is V = (pi) x R2 x H Note: "R2" means 'R' multiplied by itself = (R x R) Im not sure what im doing wrong but i cant figure the volume of my tank using this formula. what am i doing wrong? How do you know the result you're getting isn't right ? / / / / Tell me what you're doing and I'll tell you what part of it is wrong. You can use my 'message board'.

Answer 5

Multiply the cross sectional area by the height ie. ( pi x (r squared)) x h

Where pi is the constant 3.14159265....., r is the radius and h is the height (or length) of the cylinder.

Answer 6

Cylinder volume = h*pi*r*r. where h = the height or length of the cylinder and r = it's radius.

Answer 7

A cylinder is just a circle with depth so the area of the circle times the height of the cylinder gives the volume: Pi x radius2 x height.

Answer 8

The volume of the cylinder equals pi r^2 h

Answer 9

4/3 pi r^3
