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!
If the area of the base and the height of the cylinder and the cone are the same, then the volume of the cone will always be one third of the volume of the cylinder.
first you find the area of the base and then you find the area one side of the pyramid an you time it with 3 if it is a triangular pyramid or 4 if it is a square pyramid
The barrel is probably much like a cylinder. All surface area is the lateral area+the area of the base(s). In this case: SA=(d)("pi")(h)+(2)("pi")(r2) SA is surface area d is diameter of the circle base h is the height r is the radius of the base What you are doing with this equation is figuring out the circumference x the height, so you get the area of the tall part. Then you take the area of one of the bases and multiply it by 2.

2pi(r) multiplied by the height is lateral area of right cylinder. 2Pi(r) being the circumerfence of one of the bases.
If the area of the base and the height of the cylinder and the cone are the same, then the volume of the cone will always be one third of the volume of the cylinder.
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.
Well, to find the surface area of such a cylinder, one would need to find the area of the base and multiply it by two (for there are two identical bases in a cylinder), and then add the area of the "rectangle" wrapped around the cylinder. So, you could make an equation like this: ((62*pi)*2)+(16*((6*2)*pi))=SA That would simplify to approximately 829.38 ft.2, if I'm not mistaken.
You would multipy the length of the cylinder by its circumference, then add to that the area of the circle on the closed end. the formula would be: (Pi X diameter X cylinder length) + (Pi X radius X radius) For the base, the area is pi*r2. Add this area to the SA of the side, which is circumference* height, or 2pi*r*h So, the final surface area would be pi*r2 + 2pi*r*h. Because there is only one base, you only need to find the area of one circle on the bottom.
That is correct and they are measured in cubic units.

Actually, answer 1 is for the volume, not the surface area. Aside from that, there are lots of ways to bore a hole in a cylinder. If it goes from one base (a flat face) to the other (or part of the way) parallel to the axis, answer 1 is correct (for the volume). If it is not parallel to the axis, or if it is bored from the curved surface of the cylinder, it is much more complicated. Assuming, as in answer 1, that the hole goes all the way from one base to the other parallel to the axis, to get the surface area you would add the surface area of the outer cylinder to that of the hole (just the curved surface portion), and then subtract the areas of the circular holes in the two bases, each of which is pi x the radius of the hole squared. I'm assuming you know how to calculate the surface area of a cylinder. This is the area of the curved surface, which is 2 x pi x the radius x the height, plus 2 x the area of each base, which is pi x the radius squared. ========================================================== Use the formula:- Volume of a cylinder = Pi X Radius squared X Length , to find the volume of a solid cylinder. Repeat the same calculation with the same formula, to find the Volume of the cylinder of fresh air within the cylinder . Subtract the fresh air Volume from the Solid Cylinder Volume. That will be your answer . Think about your problem, then it is dead easy.
It is one of the flat circular bit, and is at the end of the cylinder.
The one alternative to find the area of a rectangle is when you are given the length of one diagonal and its slope.
Its base.
