Volume of sphere is
V = (4/3)πr³
Since the given is in diameter we need to convert it first to radius
Diameter = 2r
or
Radius = 2/d
We can now look for radius by substituting the value of diameter to the formula
Therefore
Radius = 2/3
We now have to substitute the value of radius to the formula of volume of sphere
V = (4/3)π(2/3)³
Note: π = 3.14
V = (4/3) * 3.14 * (2/3)³
Find the cube of 2/3 and multiply π to 4/3
V = 4.188790204786391 * 8/27
Multiply the two given
Therefore
Volume is 1.2411230236404121
or
~1.24 inch³
I hope it helps
