Answer:
About 904.78 inches^3
Explanation:
A beach ball is a sphere. The volume of a sphere can be found using:
v=4/3 r^3 π
First, we have to find the radius. The radius is half of the diameter, or
r=d/2
We know the diameter is 12 inches, so we can substitute 12 in for d.
r=12/2
r=6
Now we know the radius, and can substitute it in for r.
v=4/3 r^3 π
v= 4/3 6^3 π
Evaluate the exponent
v=4/3 216 π
Multiply all the numbers together
v=904.778684234
So, the volume is about 904.78 inches^3
