WebSurface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2.Visual on the figure below: A sphere's surface area can be calculated just by knowing its diameter, or radius (diameter = 2 x radius). π is, of course, the well-known … WebApr 14, 2024 · Results showed higher specific surface area BET (3.272 m 2 /g) and pore volume (0.032 cm 3 /g) for Fe-kapok than raw kapok (0.976 m 2 /g and 0.021 cm 3 /g), indicating its higher As(V) adsorption capacity. Fe-kapok was effective at As(V) adsorption despite the presence of competing ions, such as sulphate, with its high interference …
