Xiaoming's dining table is round. Mother needs a square tablecloth with a diameter of 1.5 meters and 2 meters. To make the four corners of the square tablecloth just touch the ground, how many meters should the diagonal of the square tablecloth be?

The diagonal should be 1.5 + 1.2 * 2 = 4.9 (m)
Hope to adopt

My mother is going to buy a square tablecloth for the round table at home. The diameter of the round table is 1.3 meters and the height is 1.5 meters
Mom is going to buy a square tablecloth for the round dining table at home. The diameter of the round tablecloth is 2 meters and the height is 1.5 meters. If you want to make the square tablecloth just touch the ground, how many meters should the diagonal length of the square tablecloth be? There should be a formula! And why!

That is to say, if you buy a tablecloth with a diameter of 4.3, you can just touch the ground

The diameter of a round tea table table is 1m. How many square meters is its area?

3.14 × (12) 2 = 3.14 × 0.25 = 0.785 (M2); a: its area is 0.785 m2

A round dining table is 2 meters in diameter and 1 meter in height. If the four corners of the square cloth just touch the ground, the area of the cloth is?

According to you, the diagonal of the cloth is 4m, so its area should be:
（4÷√2）²＝8M²

Cut some square pieces of paper 3cm long and 2cm wide. How many pieces of paper do you need to make a square?
What is the relationship between the side length of a square and the length and width of a rectangle?

The side length of a square is a common multiple of 3 and 2;
Minimum = 2 × 3 = 6;
At least = 6 ﹣ 3 × 6 ﹣ 2
=2×3
=6 sheets
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

Ding cut some 8 cm long and 6 cm wide rectangular pieces of paper. At least a few pieces of paper are needed to make a square

The least common multiple of 8 and 6 is 24, so the minimum square side length of rectangular paper is 24cm;
You need 24 * 24 / (8 * 6) = 12 pieces of paper like this

In a rectangle 8 cm long and 6 cm wide, cut out the largest circle with an area of () square cm
A. 18.84B. 28.26C. 25.12D. 50.24

According to the meaning of the question, the diameter of the largest circle is the width of the rectangle, then r = 6 △ 2 = 3 (CM), 3.14 × 32, = 3.14 × 9, = 28.26 (square cm); answer: the area of the circle is 28.26 square cm

Cut the largest square from a rectangle 8 cm long and 6 cm wide. What's the figure left? What's its area in square centimeter?

The rest is rectangle, area = 2 * 6 = 12cm2

Cut out the largest semicircle on a rectangular piece of paper 8 cm long and 3 cm wide. What is the area of the semicircle in square centimeters?

The area of this semicircle is 14.13 square centimeter

A rectangle can be cut into two squares. The perimeter of the two squares is 8 cm longer than that of a rectangle. How many centimeters is the perimeter of the original rectangle

Sunshine beach,
A pair of opposite sides (the side of a square) are produced by one cut
8 △ 2 = 4 (CM)
The circumference of the original rectangle is:
4 × 4 × 2-8 = 24 (CM)
