Answer:
V ≈ 16.333 in³
Step-by-step explanation:
Formula of the Volume of a Sphere: 
V =
× (3.5)²π
V =
× 12.25π
V ≈ 16.333 in³
Find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve
