Elementary Mathematics Fill in the Blank Solving Process

1.Cylinders of equal height have more cubic centimeters than the volume of the cone, and if their base radius is 3 cm, then their height is (5cm).

2.A cylindrical ventilation pipe was 8 meters long, and since it had to be cut off by 3 meters, his surface area was reduced by square meters. Originally, the side area of the ventilation pipe was (24 square meters).

sqm) 3.A cylindrical bucket, the circumference of the bottom surface is centimeters, the water surface is 3 decimeters from the barrel mouth, and then fill the bucket with ( ) liters of water.

3dm=30cm

10*10*cubic centimeter) =

The volume of a cone is 16 cubic centimeters, and the base area is 6 square centimeters. Its height is (8) cm.

16*3/6=8cm

1.(5cm)

2.(24 sqm) sqm).

3.(liter 3dm=30cm 10*10*cubic centimeter)=4.(8) cm 16*3 6=8cm

1.Answer: 5 cm The volume of the cylinder is 3*3*height The volume of the cone is 1 3*3*3*height The volume of the cylinder minus the volume of the cone is to find the height.

Square metre.

One, 5cm two, square meters (divided by 3 times 8 equals.

Three, four, 8cm

It takes 33 minutes, fry 11 cakes, fry 2 first, fry 4 pans, a total of 8, it takes 24 minutes, the remaining 3 fry two first, and when one side is cooked, pick up one of them, and then turn the other, it takes 2 three minutes, fry one of them and then put that one in it, a total of 33 minutes.

Hypothesis 1: If one side of the pancake can be fried on one side of the other pancake, the time to exchange pancakes in the middle is negligible. The answer is 11 * 3 = 33 minutes.

Hypothesis 2: If one side of a cake is fried, only the other side of the cake can be fried. The answer is 10 * 3 + 3 + 3 = 36 minutes (this answer is more realistic, and it takes 6 minutes for the last cake to be fried separately.) That's a good answer).

Two in a group; Divided into 5 groups, single plus one; 3 minutes on one side; 5 sets take 3*2*5=30 minutes; Individual 2 x 3 = 6 minutes: Total 30 + 6 = 36 (minutes).

Total 11x3=33 points.

First of all, you can use binary once, but the teacher will definitely say it, so I will explain what I solved with arithmetic, three minutes on one side, six minutes on both sides, 2*3=6,11 2=5....1 (times) It needs to be completed six times, and you can get points with 6*6.

11÷2=5...1 (time) takes six times to complete.

2 3 = 6 (minutes every two).

6 6 = 36 (minutes).

A simplest fraction, the numerator expands to 3 times its size, and the denominator is reduced to its 3 branches 1 equals 3 branches 1, this fraction is (1/27), and the fraction unit is (1/27).

20% of a shipment was shipped out on the first day and the remaining 15% on the second day, which was less than the original (32%)

There was a batch of steel on the site, 500 kg was used on the first day, 30 kg less than one-fifth of the total, one-third of the total was used on the second day, and 883 and 1/3 kg of steel was used on the second day.

In a village, ammonia is needed to fertilize corn. To make 100 kg of 15% ammonia water into 5% ammonia, add (200) kg of water.

A flour mill produces three-fifths of a ton of flour per hour, and it takes (five-thirds) an hour to produce 1 ton of the same flour.

The reciprocal of one-half is (400)% of itself

Divide a 7-meter-long rope into 5 equal sections, each of which is 1/5 of the total length

The product of a number and its reciprocal gives 2 and a third, the reciprocal of this number (3/4).

Lack of conditions: the number of people who love both table tennis and volleyball The method is as follows: The total number of students = the number of people who love football + the number of people who love volleyball + the number of people who love table tennis - the number of people who love both table tennis and volleyball - the number of people who love both football and volleyball + the number of people who love both three kinds of balls 54 = 20 + 30 + 40 - the number of people who love both table tennis and volleyball - 14-12 + the number of people who love all three kinds of balls So the number of people who love all three kinds of balls =54-20-30-40 + 14 + 12 + the number of people who love table tennis = 10 + the number of people who love both table tennis and volleyball.
