WebThe formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given the diameter of the sphere, you can first calculate the radius, then the volume. Created by Sal Khan and Monterey Institute for Technology and Education. Sort by: WebThe area of the whole surface is then obtained by adding together the areas of the pieces, using additivity of surface area.

WebMar 2, 2024 · To calculate the surface area of a sphere, all you need to know is the sphere's radius - or its diameter. A = 4 × π × r² where r is the radius. As we know that the diameter of a sphere is equal to two radii d = 2r, we can transform the equation into another form: A = 4 × π × (d / 2)² = π × d² where d is the sphere diameter. WebThe surface area of a sphere is the total area that is covered by its outer surface. The surface area of a sphere is always expressed in square units. The formula for the surface … Websolid equals its surface area when the volume and the surface area are functions of R. Figure 10 uses an octahedron to exemplify the relationships between the radius R of the sphere inscribed in the solid and the radius r of the circle inscribed in a face of the solid. Then V(R) = MSR/3 where R is the radius of inscribed sphere, S is the ... dwarf french bean compass
