• (BANGUN RUANG SISI LENGKUNG)
•  2. Understanding properties of cylinder, cone and sphere, and find its size 2.1 Identify elements of cylinder, cone and sphere 2.2 Counting surface area and volume of cylinder, cone and sphere 2.3 Problem solving which related by cylinder, coe and sphere
• 2.1 Identify elements of cylinder, cone and sphere 2.2 Counting surface area and volume of cylinder, cone and sphere2.3 Problem solving which related by cylinder, coe and sphere
• Top / lid of cylinderRight face/blanket /curvedsurface Based of cylinder
• Area of top+base=2πr2.
•  Curved surface = area of rectangle l = perimeter of circle Wide = height of cylinder
•  1. Given that :h = 15 cm, r = 7 cmFind :a. The area of curved surfaceb. The surface area of cylinder
• a) . The area of the curved surfaceb) . The surface area of the cylinder3. Find the height of cylinder if gifen that the area of the curved surface is 880 cm², the base diameter is 14 cm.4. Find the heght of a cylinder whose base radius is 15 cm, surface area is 5, 181 cm².
•  a). The base radius b). The height of the Cylinder6. The area of the curved surface of a cylinder is 251.2 cm². If the ratio of the base radius to the height is 2 :5, find :a) Base radiusb) The height of cylinder.
