That depends on what you already know about it. Formulas are just relationships between what you do know and what you don't know. I can't tell you what formula to use until you tell me what you know.
Example:
If you know the volume of the cylinder and its radius, then Height = Volume / pi xradius2
If you know the area of the cylinder and its radius, then Height = Area / 2 x pi x Radius
If you know the volume and area of the cylinder, then Height = Area2 / 4 x pi x Volume
L.A.= 2*pi*radius*height its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
Area of a circle = (pi)r2 [Areacircle = pi time the radius squared.] Volume of a cylinder = (pi)r2h [Volumecylinder = pi times the radius squared times the height.] (This applies to a right circular cylinder. :)
using a protractor
pi * radius2 * height
that formula is base times height
Volume of a cylinder = pi*radius2*height
pi x r2 x height
V= AxH where A is the area of the circle, and H is the height of the cylinder.
2πrh, where 'r' is the radius and 'h' is the height.
The answer depends on what information you are given: volume and height, or surface area and height, etc.
L.A.= 2*pi*radius*height its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
π R² H Pi radius squared by height
Finding the volume of a cylinder is similar to finding the volume of a prism because both involve calculating the area of the base and then multiplying it by the height. In a cylinder, the base is a circle, so the formula for the area of a circle (πr²) is used. For a prism, the base can be any polygon, and you multiply the area of that base by the height of the prism. In both cases, the formula is Volume = Base Area × Height.
Area=Bh when B=area of the base, and h=height of the prism/cylinder
pie (3.14) x radius^2 x height
V = (pi * radius * radius * height)/2 ie. formula for the volume of a cylinder divided by 2
divide the volume by 2*pi*r where r is the radius of the base
