Calculate the surface area and volume of cylinder (unit: cm) & nbsp;

Side area: 2 × 3.14 × 10 × 5 = 314 (square centimeter) bottom area: 3.14 × 102 = 314 (square centimeter) surface area: 314 + 314 × 2 = 942 (square centimeter) volume: 314 × 5 = 1570 (cubic centimeter) answer: surface area is 942 square centimeter, volume is 1570 cubic centimeter

Figure surface area and volume in CM
The right figure is a machine part. The surface area and volume of the part are calculated according to the dimensions in the figure. It is composed of a cylinder and a cuboid. The cylinder is on the cuboid. The data cylinder is 8cm high and 2cm in diameter. The cuboid is 10cm long, 5.6CM wide and 6cm high

Area = 16 μ + 374.4cm & # 178;
Volume = 8 μ + 336cm & # 179;

Calculate the surface area and volume of the following figures. (unit: cm) (formula)
1. What is the surface area and volume of a cube with a length of 6cm?
2. A cuboid is 2cm high, 4cm long and 3cm wide. What is its surface area and volume?

1. The area of each surface is 6 * 6 = 36 square centimeter, with a total of six surfaces 36 * 6 = 216 square centimeter
Volume is base area times height = 6 * 6 * 6 = 216 cubic centimeter
2. Surface area:
(2 * 4 + 3 * 4 + 2 * 3) * 2 = 52 square centimeters
Volume: 2 * 3 * 4 = 24 CC

Cut out the shadow part of a rectangular cardboard according to the figure below, just to make a cylinder. Calculate the surface area and volume of the cylinder (to be explained)

1. Because the length of the shadow rectangle is 18.84, which is exactly the circumference of the circle surrounding the bottom of the cylinder
2. Radius of bottom circle: 18.84 ÷ (3.14 × 2) = 3 (CM)
3. Diameter: 3 × 2 = 6 (CM)
4. Width of shadow rectangle (also height of cylinder): 10-6 = 4 (CM)
5. Surface area of cylinder:
π×6×4＋2π×3²……………… It's simple here
=24π＋18π
=42π
=131.88（cm²）
6. Volume: 3.14 × 3 & # 178; × 4 = 113.04 (CM & # 179;)
