The diameter of a sphere is 3 inches which equation can be used to find the volume of the sphere in cubic inches
The equation that can be used to find the volume of a sphere in cubic inches is:
V = (4/3) * π * r^3
However, since we are given the diameter (which is twice the radius), we need to find the radius first. The radius (r) can be obtained by dividing the diameter (d) by 2:
r = d/2
In this case, the diameter is 3 inches, so the radius would be:
r = 3/2 = 1.5 inches
Now, we can substitute the value of the radius into the volume equation:
V = (4/3) * π * (1.5)^3
Therefore, the equation to find the volume of the sphere in cubic inches would be:
V = (4/3) * π * 1.5^3
