Formulas of all shapes in mathematics from grade one to grade six? Urgent! Urgent! Urgent!
The formula of primary school graphics can be classified according to plane graphics and three-dimensional graphics, as follows:

The first type: plane graphics

1. triangle

Area = bottom × height ÷2, that is, S=a×h÷2.

Perimeter = sum of three sides, that is, l = a+b+c b+c.

2. circle

Area = π× the square of radius, that is, S = π * R 2 = π * D 2/4 = L 2/4π, (D: diameter, L: circumference).

Circumference = diameter × π, that is, L = 2π r = π d.

3. Fan shape

Area s = n π * r 2/360 = ar 2, (n: central angle of the sector, a: arc system of the central angle of the sector).

Circumference L=nπR/ 180+2R=aR+2R.

4. Square

Area = square of side length, that is, s = a 2.

Perimeter = sum of four sides, that is, L=4a.

5. Rectangular

Area S=ab.

Perimeter l=2(a+b).

6. Parallelogram

Area S=ah=absinx, (A: bottom, H: height, adjacent side of B:A, included angle of X:A and B).

Perimeter L=2(a+b).

7.diamond shape

Area S=ab, (A and B are the lengths of two diagonal lines).

Perimeter L=4x (x is the side length).

8. trapezoid

Area S=(a+b)h/2, (a, b are the upper and lower bottoms, and h is the height).

The area of isosceles trapezoid is S=csinA(a+b)/2, (c is waist and a is acute angle).

9. ring

Area s = (r 2-r 2) π, (r outer circle radius, r inner circle radius).

The second type: three-dimensional graphics

1. ball

Surface area s = 4 * π * r 2.

Volume v = 4 π r 3/3.

2. Cubic

Surface area s = 6a 2.

Volume v = a 3.

3. Cuboid

Surface area S=2(ab+bc+ac).

Volume V=abc.

4. Prism

Volume V=Sh, (s: bottom area, h: height).

Step 5: Cylinder

Surface area s = 2π rh+π r 2, (r: radius of bottom circle, h: side height).

Volume V=Sh (S: bottom area, h: height) = π r 2 h.

6. Cones and pyramids

The surface area of the cone is s = π rh+π r 2, (r: radius of the bottom circle, h: side length).

The volume of cone and pyramid V=Sh/3, (s: base area, h: height).

7. Prism

Let the areas of the top and bottom surfaces of the prism be S 1 and S2, respectively, the height be h, and the volume be v = (1/3) [s1+√ (s1S2)+S2] × h, (√ stands for square root).

8. Cone table

Volume v = [s+s'+√ (SS')] h÷ 3 = π h (R2+RR+R2)/3, (r- upper bottom radius, r- lower bottom radius, h- height).
