you find the radius of a cone by the bottom of it or the round part
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
Three dimensional objects, such as a cone, do not have a perimeter in any meaningful way.
Measure the depth using a metric ruler!
Volume of a cone = 1/3*pi*radius2*height
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!
A cone does not really have a base but if you find the circumference of the bottom that is the base.
That depends what you are given. If you have an actual cone, you can measure the diameter of course.
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
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
