Depends on the problem; many 3D figures have 2D faces/shapes within them. One can say "find the perimeter of a cylinder," and the question could be interpreted as finding the perimeter of one of the circular bases of the cylinder. Use common sense, and find out what the question is asking.
There is no perimeter of a circle. Only flat shapes have perimeters. You can however, find the circumference, surface area, and volume.
circumference is the perimeter of a circle. a circle is 2 dimensional. volume is 3 dimensional. you need to state what shape it is. I could guess that you are talking about a cylinder. the volume is pi.r2.h, if you find the radius from the volume, you can find the perimeter of the circle by 2.pi.r
Here's how to do that: 1). Find its length. 2). Find its perimeter. 3). Divide (its length) by (its perimeter). The quotient is the ratio of its length to its perimeter.
To find the perimeter you add and to find the area we multiply.

The concept of a perimeter makes sense only in the context of a 2-dimensional object (or a sphere).
Let h be the height of the cylinder and r the radius of the circular top/bottom. If you cut the cylinder down one side and roll it out, you have a rectangle. The length of the side is h and the width would be 2pi*r (the perimeter of a circle). Therefore, the perimeter of a cylinder is 2pi*r + 2h

If you know the perimeter, there is no need to find it again.

perimeter of what quadrant?
The perimeter of a triangle is the distance around it. Add the lengths of the three sides to find the perimeter.
Pi is used to find the area and perimeter of a circle and the volume of a sphere, cylinder, and cone. Pi=3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230664709384460955058223172535940812848111745028410270193852110555964462294895493038196... That was 200 decimal places of Pi.
