WebbThe 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: Webb8 apr. 2024 · The volume of a sphere is the three-dimensional space occupied by a sphere. This volume depends on the radius of the sphere (i.e, the distance of any point on the surface of the sphere from its center). If we take the cross-section of the sphere then the radius can be calculated by reducing the length of the diameter to its half.

WebbIf the diameter of the sphere = 2r, then the surface area of the sphere = 4πr 2 square units. The area of a sphere is always expressed in square units, like m 2, in 2, cm 2, yd 2, etc. The volume of a sphere is the total amount of capacity immersed in a sphere that can be calculated using the volume formula for the sphere which is V = (4/3)πr 3.
