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
The formula for finding the perimiter of a rectangle is add up all of its sides
Area of a rectangle: a = l * w
A rectangle has no volume, it is a 2 dimensional object.
It is: 2*pi*radius
diameter/2
Multiply the base by the height !
A = lw Area of a rectangle = length times width
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.
The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume
this is called finding the circumference. The formula is 2*pie*radius
Area of circle = pi*(radius)2
