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: WebSurface area of a hemisphere A hemisphere is half of a sphere although the surface area of a hemisphere is not half of the surface area of a sphere. This is because we have an extra circular face that we have to add onto the surface area of the curved face.
