1. Chapter II Characteristics of cylinder, Cone, and sphere, and determining the size

2. A. Cylinder 1. Elements of cylinder a. Base side of cylinder b. Center of circle c. Radius of circle d. Diameter of circle e. Height of cylinder f. Cover of cylinder. 2. The large cylinder The large of cylinder= large of stand side+ large of top side+ large of the base side = large of stand side + 2 large of base side 3. Volume of cylinder Volume of cylinder can be mentioned as the following: V = A × t V = (π r 2 ) × t

3. B. Cone 1. Elements of cone a.Bas side of cone b.Center point c.Radius of base side of cone d.Diameter of base side of cone. e.Height of cone f.Chord base side of cone g.Cover of cone 2. The large of sides The large of cone’s side L= πrs + πr2 With r = radius of cone s = the length of drawing line

4. 3. Volume of cone Formula of volume of cone : With r : radius and t : height of cone C. Sphere 1. Elements of sphere a.Point O is central point b.Radius of sphere c.Diameter of sphere d.Cover of sphere e.Chord of sphere f.Drawing line of sphere

5. 2. The large of sphere’s cover Large: L = 4 r 2 With r : radius of sphere 3. Volume of sphere Formula for the volume of sphere: V = 3∕4 π r 3 With π = 3,14
