Geometry Cheat Sheet Circle Formula Surface Area Formulas Che Surface area = ba la example: ba = base area = 16cm2 la = lateral area (all sides) = 60cm2 surface area = 16 60 = 76cm2 surface area = fa × s example: fa = area of one side = 200cm2 s = number of sides = 12 surface area = 200 × 12 = 2400cm2 surface area = 4 × π × r2 example: r = radius = 4.5cm surface area = 4 × 3.14 × 20.25 = 254.5. Volume and surface area formulas, set of 8 posters, math, geometry, educational posters, classroom wall art, printable, digital download each poster features a different geometric figure, including a cube, rectangular prism, cone, triangular pyramid, triangular prism, square pyramid, cylinder, and sphere. The total surface area formula of cone = t = πr (r l) =3.14 × 6 × (6 9) =282.6 inches 2. ∴the surface area of cone will be 282.6 inches2. example 3: using the surface area formula of the cube find the surface area of the cube whose side is 4 inches. solution: given side length of cube = 4 inches. Surface area meaning. sa = 2b ph s a = 2 b p h. find the area of each face. add up all areas. sa = b 1 2sp s a = b 1 2 s p. find the area of each face. add up all areas. sa = 2b 2πrh s a = 2 b 2 π r h. find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height.
