May 07, 2011 · The surface area of the (n − 1)-sphere of radius 1 is where Γ(z) is Euler's Gamma function. Another formula for surface area is and the volume is the surface area times or Generalization to metric spaces. More generally, in a metric space (E,d), the sphere of center x and radius r > 0 is the set of points y such that d(x,y) = r.

Prediksi shio sidney 2020The circumscribed cylinder for a given sphere has a volume which is 3/2 times the volume of the sphere, and also the curved portion has a surface area which is equal to the surface area of the sphere. This fact, along with the volume and surface formulas given above were known as far back as Archimedes.

To calculate the volume and surface area, you need to know the radius and height. Given the diameter is 33.7 ft, the radius is half of the diameter, or Thus the volume is ( )( ) Note, the surface area should only include the “top” of the cylinder as the “bottom” is on the ground (leading into the root system of the tree).
