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.
The area for the base of a cylinder is the area of a circle. pi times radius squared.
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.
First, you figure out what the area of the top of the cylinder is, which in case is pi times radius squared. Then, you multiply the answer by two. Next, you find the lateral surface area of the cylinder by multiplying the circumference times the height. Since the problem only gives us the radius of the cylinder, we use the formula, two times pi times radius times the height, in order to find the lateral surface area of the cylinder. Now the final step. Add the answer you got for the first step, plus the lateral surface area of the cylinder, and this should give you the surface area of the can of soup.
1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!

The area of the base of a cylinder is: pi times radius squared
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.
if the cylinder is on the inside, it would not affect the surface area. otherwise, subtract the part of the inside cylinder that touches the outside from the cylinder
To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
Find the cross-sectional area of the cylinder (pi x the radius2), the multiply that by the height of the cylinder
(2)(pie)(r)(h) + (2)(pie)(r - squared) = tot area of a cylinder
