Answer:
Third one
Step-by-step explanation:
The circumference of a circle is given by the formula:
- P = d*π
- d is the diameter
P= 20π ⇒ d*π = 20π ⇒ d= 20
The volume of a sphere is given by the formula:
- V = [tex]\frac{4}{3}[/tex]*π*r³
- r is the radius wich is d/2
- r = 20/2 = 10
V= [tex]\frac{4}{3}[/tex]*π*10³
V= 1333.33*π
