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 |
| 3 |
| V = | 4π(33) |
| 3 |
| V = | 4π(27) |
| 3 |
| V = | 108π |
| 3 |
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
d = 6
V = 36π or 113.0973
A = 36π or 113.0973
