Answer:. 1. A cylinder has (3) faces. The areas of the two (bottom) surfaces are equal, and the side surfaces can be unfolded into a rectangle. The length and width are (the height of the cylinder) and (the circumference of the bottom) respectively.
2. The radius of the bottom surface of the cylinder is 3cm and the height is 5cm. Its bottom area is (28.26) cm2, lateral area is (50.24) cm2, and its surface area is (106.77) cm2. Its volume is (14 1.3).
3. The diameter of the cone bottom is 20 decimeters, the height is 9 decimeters, and the volume is (942) cubic decimeters.
4. The distance between Party A and Party B is 20km, and the distance drawn on the map is10cm. The scale of this map is (1:2000000).
The length of a precision part is 4 mm, and the length drawn on the drawing is 4 cm. The scale of this drawing is (10; 1)。
6. Choose four numbers from 2, 4, 6, 3 and 9 to form a proportional formula (9:3=6:2).
7. Just process a cylinder with a volume of 129 cubic centimeter into the largest cone part. The volume of this cone part is (43) cubic centimeters, and the cutting volume accounts for (2/3) of the cylinder volume.
