WebIt may seem that way, but technically, a sphere is a 3-D shape (has width, height, and depth) and a circle is 2-D (width and height) A circle is missing the depth needed to become a 3-D shape. Also, you find volume for spheres and area for circles. This then changes the formulas. Circle: A = pi*r^2 Sphere: V = 4/3*pi*r^3 WebCylinders have either 2 or 3 faces, 0 or 2 edges, and 0 vertices. Cone. Cones have either 1 or 2 faces, 0 or 1 edges, and 1 apex (which is described by some mathematicians as a vertex). Triangular Prism. Triangular Prisms have 5 faces, 9 edges, and 6 vertices. The two faces at either end are triangles, and the rest of the faces are rectangular.
WebThe surface area of a right circular cone is defined as the total region covered by the surface of the 3-D dimensional shape. It is expressed using square units, like cm 2, m 2, in 2, ft 2, etc.Let us cut and open up a right circular cone, to understand about the surface area. The curved surface forms a sector with radius 's', as shown below.
