The calculation formula of various graphic areas should be detailed.

Perimeter of rectangle = (length and width) ×2 perimeter of square = side length ×4 area of rectangle = side length × area of triangle = bottom × height ÷2 area of parallelogram = bottom × high trapezoid = (upper and lower bottom) × height ÷2 diameter = radius × 2 radius = diameter ÷ surface area = (length × Volume of cylinder = bottom area × perimeter c and area of square with high-level graphic name symbol s A- side length C = 4as = A2 rectangle A and B- side length C = 2 (AB) S = half the height S of AB triangle A, B, C- perimeter inner angle on the side s-H-A and C- where S = (ABC)/2S = Ah/2 = 1/2 = A2 sinb sinc/(2 Sina) quadrilateral d, and b side length H-A side height α-included angle S = ah = ABS in α rhombus a side length α-included angle D- long diagonal length D- short diagonal length S = DD/2 = A2Sinα trapezoid a and B- upper and lower base length H- height M- midline length s = 2 = MH circle R- radius D- 4 sector R- sector radius A- central angle C = 2r+2π r× (a/360) S = π R2× (a/3602 = π α R2/360-b/2 [R2-(b/2) 2]/kloc-0. 4 Cube graphic name symbol area S and volume V Cube A- side length S = 6A2v = A3 Cuboid A- length B- width C- height S = 2 (ABAC BC) V = ABC prism S- bottom area H- height V = SH pyramid S- bottom area H- height V = SH/3 On the prism S 1 and S2-, Bottom area H- height v = h [s1S2 (s1)12]/3 prismatic shape S 1- upper bottom area S2- lower bottom area S0- middle cross-sectional area H- height v = H (S 1 S2 6 cylinder r- bottom radius H- height c- bottom perimeter S- bottom area s side-lateral area s table-surface area c = 2π r s bottom = π r s side straight cone r- bottom radius h. 3 frustum r- upper bottom radius r- lower bottom radius h- height v = π h (R2+RR+R2)/3 ball r- radius d- diameter v = Bottom radius h- height v = π h [3 (r 12+R22) h2]/6 Annulus R- Annulus Radius D- Annulus Section Radius D- Annulus Section Diameter v = 2π 2RR2 = π 2d2/4 Barrel D- Barrel Belly Diameter D- Barrel Bottom Diameter h- Barrel Height V = π.
