The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume

V = (pi * radius * radius * height)/2 ie. formula for the volume of a cylinder divided by 2

2πrh, where 'r' is the radius and 'h' is the height.

The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.

π R² H Pi radius squared by height

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

pie (3.14) x radius^2 x height

divide the volume by 2*pi*r where r is the radius of the base

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. :)

It is: 2*pi*radius

Diameter divided by 2 = radius

The surface area of a cylinder can be found using the following formula - SA = 2(Pi*r2) + (2*Pi*r)*(H) Pi = Approximately 3.14 r = Radius of the base of the cylinder H = Height of the cylinder
