For this case we have that by definition, the volume of a sphere is given by:
[tex]V = \frac {4} {3} * \pi * r ^ 3[/tex]
Where:
r: It is the radius of the sphere
According to the statement we have to:
[tex]r = \frac {2} {2} = 1 \ft[/tex]
So the volume is:
[tex]V = \frac {4} {3} * \pi * (1) ^ 3\\V = \frac {4} {3} * 3.14\\V = 4.186[/tex]
Rounding we have that the volume of the sphere is: [tex]4.19 \ ft ^ 3[/tex]
Answer:
Option B
