Oh, dude, finding the perimeter of a cone? That's like finding the square root of a potato. Cones don't have perimeters, they have curved surfaces. If you want to find the circumference of the base, just use the formula 2πr. But seriously, who measures cones by their perimeters anyway?
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.
If you know the perimeter, there is no need to find it again.
There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
you find the radius of a cone by the bottom of it or the round part
how can you find the perimeter of a cone i.e. a 3d shape!
With great difficulty because a cone is a 3D object and only 2D shapes have perimeters

A cone is a 3-dimensional shape; the 3-dimensional equivalent of perimeter is area. See the related question for information on this.
You don't. Perimeter is a concept associated with plane figures, not solid shapes.

Pi is used to find the area and perimeter of a circle and the volume of a sphere, cylinder, and cone. Pi=3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230664709384460955058223172535940812848111745028410270193852110555964462294895493038196...

The shape described cannot be a cone since a cone has a base at one end and a point - of zero length - at the other!
If you know the perimeter, there is no need to find it again.
The area of the circle added to the area of the lateral part is the way to find the perimeter (or more commonly known as the surface area), or in this case, (pi x r2 + pi x r x l).pi=3.14r=radiusl=slant height
To find the side of a cone, you can use the Pythagorean theorem. The slant height (side) can be calculated by using the formula: s = √(r^2 + h^2), where "s" is the slant height, "r" is the radius of the base, and "h" is the height of the cone.
To find the perimeter you add and to find the area we multiply.
