Answer: B.
Step-by-step explanation:
Diameter = Radius divided by 2.
The volume formula of a sphere is V = 4/3 π r^3.
Radius of this problem = 7.5.
So, V = 4/3 π (7.5) ^3.
Once you "plug in" the radius and solve the equation, you get an answer of 1,766.3, rounded to the nearest tenth.
Don't forget the inches cubed!
