It really depends on what is known about the cone. If you know the volume (v) then depth = 3*v/(pi*r^2). There is more than one way to measure, if all else fails use a ruler.
you find the radius of a cone by the bottom of it or the round part
Three dimensional objects, such as a cone, do not have a perimeter in any meaningful way.
Depth of cone = Radius of semicircle = 28/2 cm = 14 cm Circumference of the base of cone = Arc of semicircle = 0.5*pi*28 = 14*pi cm Therefore radius of base = 14*pi/(2*pi) = 7 cm Capacity = 1/3*pi*r2*h where r is the radius of the base of the cone. = 1/3*pi*72*14 = 718 cm3
Volume of a cone = 1/3*pi*radius2*height
Measure the depth using a metric ruler!
Volume of the cone = 1/3*pi*radius2*depth = 2.945243113 or about 3 cubic km
It depends on what the cone looks like.
the cone base formula
It depends on what the cone looks like.

how can you find the perimeter of a cone i.e. a 3d shape!
That depends what you are given. If you have an actual cone, you can measure the diameter of course.
A cone does not really have a base but if you find the circumference of the bottom that is the base.
Three dimensional objects, such as a cone, do not have a perimeter in any meaningful way.
The base of a cone is the area basically so : pi(radius)^2
pls tell me how to find development for cone which is half cutted
Volume of a cone = 1/3*pi*radius2*height To find the radius make it the subject of the above formula.
