step 1: if its an open cylinder you have to find the area of both circles by doing radios times radios times pie. (pie equals 3.14). you do this for both circles.
step 2:then you find radios the radios of the rectangle

The area for the base of a cylinder is the area of a circle. pi times radius squared.
Step One: First you find the area base. Ab= (pi) x (radius²) Next you find the Volume V=Abh (area) x (base) x (height) Step two: A= ab x 2 next you find the circumference c=(pi) x (diameter) A= (length) x (width) I HAVE NO CLUE WHAT I'M DOING.
You Find the Hieght of the cylinder
First find the area of the cylinder's base, and multiply that by the height. For V = A x h. Volume, Area, height.
We assume the surface area of a cylinder excluding its ends. Area = height of cylinder multiplied by circumference. That is A = h x Pi x diameter.
