By definition, the surface area of the sphere is given by:
Where,
r: sphere radio
Clearing r we have:

Substituting values:

Then, the volume of the sphere is given by:
Substituting values we have:
Answer:
the volume of the sphere is:

Answer:
m∠1 = 81
m∠2 = 99
Step-by-step explanation:
The angles are supplemaentary and therefor sum to 180
3x + (x + 72) = 180
4x + 72 = 180
4x = 108
x = 27
m∠1 = 3x
m∠1 = 27(3)
m∠1 = 81
m∠2 = x + 72
m∠2 = 27 + 72
m∠2 = 99
