1，.The automobile sales market planned to sell 850 cars last month, and the actual sales of Qingshi were 26 percent more than planned. How many more cars were actually sold than planned?

Actual sales of more cars than planned = 850 (manual 1 + 26%) - 850 = 850 * 26% = 221 cars 2 The automobile sales market planned to sell 850 cars last month, and the actual sales were 26% more than planned. How many cars are actually sold? Actual sales of cars = 850 (1 + 26%) = 850 + 221 = 1071 units.

1，.The automobile sales market planned to sell 850 cars last month, which was actually 26 percent more than planned. How many more cars were actually sold than planned?

The actual number of cars sold = 850 (1 + 26%) - 850 = 850 * 26% = 221 cars 2 The car sales market planned to sell 850 cars last month, and the actual sales were 26% more than planned. How much of the actual sales volume of Qiqing's cars? Actual sales of cars = 850 (1 + 26%) = 850 + 221 = 1071 units.

Question 6: (1) If the diameter of the log is 40cm, then the truncated should be a square, and the diagonal line of the square should be 40cm in diameter. According to the triangle formula, we find that the side length of the largest square in the log is 20 cm.

The length of the log is 2m = 200cm, and the area of this rectangle is 20 x20x 2 + 20 x200x4 = 16800 square centimeters = square meters, and the painted area is square meters.

2) Find the volume, the side length of the cross-section square is 20cm, the height is 200cm, 20x20x200=80,000 cubic centimeters=cubic meters.

cubic meters of timber weight.

1. The side area of a cylinder is 4dm high, what is its surface area?

First I divide by 4 to calculate the bottom circumference is, then divide by to calculate the base radius is, then use, and finally use.

2. Split a 1m long log into two equal halves along the diameter, and the surface area is increased. What is the original surface area of this log?

First of all, I divide by 2 to calculate the area of a split face, then divide by 1 to calculate the base radius=, divide by 2 to calculate the bottom radius=, then calculate the two base areas, calculate the side area, and finally add the two base areas and the side area together.

3. The bottom radius of a cylindrical cup is 4cm, and the height is 10cm. If the height of the water surface in the cup is 5cm, what is the area of the inner wall in contact with the water?

First of all, I use to calculate a bottom area, because as long as it is poured in, it will touch the bottom surface of the =, and then I use to calculate the area of the water touching the side of the cup =, and finally add it together.

I'll only do the first question Answer: The surface area is equal to the side area plus the two bottom surface areas.

Multiplying by 4 equals square decimeters).

None of this? How to mix in the future?
