Answer:
Note: I am not 100% sure if I am correct, though I hope this helps:
To find the volume of a sphere in cubic inches, we need to first convert the radius from feet to inches, as the volume formula for a sphere involves using the radius in the same unit as the volume.
1 foot = 12 inches.
So, the radius in inches will be:
Radius (in inches) = x feet * 12 inches/foot = 12x inches
Now, we can calculate the volume of the sphere using the formula:
Volume = (4/3) * π * radius^3
Volume = (4/3) * π * (12x)^3 cubic inches
Volume = (4/3) * π * 1728x^3 cubic inches
Volume ≈ 7241.13x^3 cubic inches
Therefore, the volume of the sphere is approximately 7241.13x^3 cubic inches.
