Of course they can. The cone would have to be taller or have a wider base than the cylinder, but they could very easily have the same surface area. A cone and a fish can have the same surface area.
The surface area does not provide enough information to determine the dimensions of the cylinder. It could be a tall thin cylinder or a squat one. It is possible for two such to have the same surface area but vastly different volumes.
The surface area of a cylinder is measured in square units, and could be measured in square centimeters.
Could be a bad coil (each cylinder has its own) common problem
You can't tell. It can be anything. A cylinder wth a circumference of 52 can have any length. It could be 0.001 long, or it could be 35 million long, or less, or more, or anything in between. All of these different cylinders could have the same circumference, but they all have different surface areas. The surface area is (circumference) x (length). So the surface area of your cylinder is 52 for every 1.0 unit it is long.
Master cylinder possible but could also be wheel cylinder problems or warped rotors
this could be a bad plugwire or sparkplug or a bad coil for cylinder 7.
A person could show ownership of a container by rolling a cylinder over the container's wet clay surface.
Change the wire, or coil plug
Yes, it could.
The "bottom of a curved line" made by the liquid in a graduated cylinder could be called the "measuring line" or "reference line" in the application of that piece of labratory equipment. The curved surface of the liquid itself is called the meniscus, and we look to the bottom of the meniscus to make our reading as to the volume of the liquid in the graduated cylinder. The liquid in the cylinder "grabs" the sides of the cylinder and "pulls itself up" just a bit, and that creates the curve in the surface of the liquid. And that curve, the meniscus (which is from the Greek word for crescent), leaves us with a problem: where do we "read" the volume marked off by the graduations along the side of the cylinder? And the answer is, "At the bottom of the meniscus."
A cylinder could also be called a column or a tube.
