Answer: C.
Step-by-step explanation:
Diameter = Radius/2
So, the radius would be 6.5 in.
The formula for the volume of a sphere is: V = 4/3 (3.14) r^3.
So, once you "plug in" the radius, you get an equation of V = 4/3 (3.14) r^3.
And, once you solve the equation, you get and answer of 1,150 in.^3, rounded to the nearest cubic inch.
