Enter one value below
A sphere has a diameter of 40
Calculate the radius, volume, and surface area.
Calculate radius (r):
We know that d = 2r
Rearranging the equation, we get:
| r = | d |
| 2 |
| r = | 40 |
| 2 |
r = 20
Calculate Volume (V):
| V = | 4πr3 |
| 3 |
| V = | 4π(203) |
| 3 |
| V = | 4π(8000) |
| 3 |
| V = | 32000π |
| 3 |
V = 10666.6667π or 33510.3217
Calculate Surface Area (A):
SA = 4πr2
SA = 4π * 202
SA = 4π * 400
A = 1600π or 5026.5482
Final Answers
d = 40
r = 20
V = 10666.6667π or 33510.3217
A = 1600π or 5026.5482
