Enter one value below


A sphere has a radius of 3

Calculate the Volume, diameter, and surface area.

Calculate diameter (d):

d = 2r

d = 2 * 3

d = 6

Calculate Volume (V):

V  =  4πr3

V  =  4π(33)

V  =  4π(27)

V  =  108π

V = 36π or 113.0973

Calculate Surface Area (A):

SA = 4πr2

SA = 4π * 32

SA = 4π * 9

A = 36π or 113.0973

Final Answers

r = 3
d = 6
V = 36π or 113.0973
A = 36π or 113.0973
