Enter one value below


A sphere has a surface area of 10

Calculate the radius, diameter, and volume.

Calculate radius (r):

SA = 4πr2

Dividing each side by 4π, we get:


Cancel 4π from each side

r2  =  SA

r2  =  10

r2  =  10

Take the square root of both sides

r = √0.79577471545948

r = 0.89206205807639

Calculate diameter (d):

d = 2r

d = 2 * 0.89206205807639

d = 1.7841241161528

Calculate Volume (V):

V  =  4πr3

V  =  4π(0.892062058076393)

V  =  4π(0.70988043043793)

V  =  2.8395217217517π

V = 0.9465π or 2.9735
